In exams, I would parrot that addition polymers add monomers without losing molecules, like nylon 6,6, while condensation polymers lose small bits like water, like Bakelite. But the truth is, I only saw them as names to underline in my notebook, not as things. The real difference I understand is between my chacha's old machine parts—each link solid and complete—and the sticky tamarind glue from fresh imli that binds and changes as it sets. My book-knowledge never felt as true as that.
