I think the person you responded to might not have fully realised their own age maybe? It’s happened to me before.
I was at a festival waiting for a band to come on. Talking to people in the audience one of them asked me if I’d seen this band before. I said “yes, in X year”. A girl there says " Wow, I was born in X year". For a second I wondered how she got the beer she was holding then quickly calculated that X year was 18 years previous to the current one and realised I was talking to a group of people roughly half my age. Nothing wrong with that but it just felt kind of weird that I hadn’t really been cognisant of it before that moment.
