Still the same person
We start speaking to older people differently. Slower. Louder. Simpler. Kindly meant, almost always.
But the person inside has not changed. They still have opinions about music, things they have never told anyone, and a sense of humour that is often sharper than ours.
Ageing changes what a body can do. It does not change who is in there.
What did you learn about someone older only after you started asking them real questions?
