This makes me think of a question my friends/family kept asking a few years back..
"Don't you ever get tired of playing video games?"
I would try to explain that it is a hobby, just as much as reading books or watching movies (even if I was/am a bit obssesive). They would keep on asking (rephrasing the question) and I would get annoyed and then ask if they got tired of watching movies, reading books, or playing computer games.
