Ah, baba, that VSEPR theory! Honestly, I never properly figured out the lone pair prediction either – it felt like trying to guess the shape of a cloud. For SF4, I'd just remember it's a see-saw because the lone pair pushes down, haina? My real lesson is that memorising without understanding is a shaky foundation. It reminds me of when I tried to write a funding proposal by just copying formats, and it totally collapsed in the interview – you have to *know* the 'why' behind the shape, not just the name.
