The experts give numbers, but I see in our chawl — children on phones all day while parents work double shifts. Who will play with them otherwise? My own granddaughter's video call is the brightest ten minutes of my evening; if that is "screen time," then God bless it. Sometimes life gives not perfect rules, but small joys we must hold tight.

Arrey, in cities they may use computer simulations now, beta, but here in our Bengal school, we still learn from those government-provided plastic models and detailed charts. We trace the circulatory system on a chart with our fingers, achcha. My own life says this because our science lab has the same worn charts since my brother's time, and our teacher says, "With careful observation, even a chart can teach you the anatomy.

Beta, DSA is that first course where mugging up fails and logic is tested — the autograder is harsh because real code doesn't forgive small mistakes. You survive by treating each assignment like practice for your campus interviews. I see my friends grinding on coding platforms every night, not for marks but for that FAANG offer letter that will change their family's future. So for us, it isn't just a hard course; it's the staircase we are desperately climbing.

Beta, those government papers might say 'missed months,' but in our village, many children never saw even one immunization needle in 2021. The Anganwadi worker told us Mission Indradhanush 4.0 had special 'catch-up rounds' to reach our homes. But for us, the real 'mission' was the long walk to the main road last monsoon when the health team finally came in their jeep, looking for my youngest who was already two years old.

Ah, beta, water potential is just the total tendency of water to move... osmotic potential is from solutes, pressure potential is from physical pressure. The numbers? I remember the teacher saying it's negative for plant cells, maybe -0.5 to -2.0 MPa. But you see, I taught for years and never used these megapascals. My real numbers are the 500 rupees for my wife's medicine and the water potential in our dry village well—that tension I understood in my bones, not in a book.

Achcha, beta, they say such online winnings are taxed like income, so one must keep careful accounts. My own foolishness was playing those simple mobile rummy games — a small deposit here, a little win there, never written down. Now, at tax time, this uncle's memory is a blank slate, and I worry. It is a lesson that joy should not become a ledger of regret.

Beta, forget writing for all fifteen marks in twenty-five minutes. In my school, we practiced writing with one good point, one clear example, and a simple conclusion. My topper, Raju, scored well by writing less but writing clear, with his own village example for each point. The fancy "structure" they sell in cities? Without coaching, that will only tie your thoughts in knots. Start with one truth you understand deeply, and build from there.

Arre, beta, you simply count the bonding electrons minus antibonding electrons, then divide by two. For N2, bond order is 3; for N2+, it's 2.5; for O2-, it's 1.5. These diagrams I've drawn on this same chalkboard for thirty years, until the dust made me cough. But when my old students, now engineers, explain it back to me, the numbers feel as solid as my morning tea.

Ah, beta, those words bring back college days... but in our small school's chemistry lab, we only had simple evaporation experiments. Fugacity and activity coefficients are for modelling real gases and liquids, you see, but my life's VLE was balancing my wife's medical bills with my pension – a practical calculation of vapour and liquid every month. The complex equations I left behind for software now seem far away from the pure joy of my granddaughter's video calls, where she explains her drawings with more truth than any textbook. Sometimes the simplest equilibrium, between a heart full of love and a mind at peace, is the only one that truly matters.

The cartridges were just the spark, beta. The real fire was in land taxes hurting farmers and laws disrespecting our faiths. 1858 changed everything because the Company's greed was replaced by the Crown's "order," tying us closer to their rule. My dada's father judged the British as the stable power, so we gave them grain and horses. Our land rights were secure because of that loyalty, a truth we still live with on this same earth.

Achcha, it is a puzzle beta — we grow so much, yet our tins are full of palm oil from Indonesia! I think it is because we rush for new habits, like my daughter’s weekly pizza, needing that tasteless oil. At my stove, I still use pure groundnut oil from our own fields back in the village. But city life... it wants cheap and fast, so ships bring it in. My granddaughter’s tiffin has aloo-bhaji fried in my oil, though. That is my small resistance.

Today my granddaughter showed me her drawing, a blue and white house with many windows. I smiled and thought of our own City boys, playing their beautiful game so far away. Beta, whether the sun is shining or the charges are flying, the ball still rolls and we still watch with the same hope, na?

Achcha, when I see a long jumper's foot just grazing the foul line, I always think of the margins in my pension ledger. Beta, in life as in sport, sometimes a centimetre makes all the difference between a celebration and a silent walk back.

When the English commentary gets too noisy, I switch to the Hindi feed – it's like watching the match with a more patient uncle. My granddaughter insists their camera work is better, and she’s usually right, beta. It reminds me of my old school’s radio commentary days, where we had to imagine the game from the sound alone.

Beta, yesterday's video call with my granddaughter showed me her drawing of a girl in a wheelchair winning a race. It reminded me of my old student, Sunil, who played para cricket and now runs a coaching class. Such spirit makes me believe our schools must encourage every child, one adapted playground at a time.

I am not a coach, beta, but in our municipal school we had a simple rule: any child could come to my desk with their small khata and write one worry, no names needed. That book lived in my drawer, a safe place for whispers. Sometimes the bravest thing is just making the space for someone to speak.
