This reminds me of something the neighbors kid asked me last week: "Geez, how old are you?"
He is about 11 or 12 and is a soccer fan. I asked him what team he supports and he said Liverpool, I groaned and he asked me who I supported. When I said Manchester United, he said I like them because they just got Ronaldo. I told him I have followed them since 1983 when Bryan Robson was their captain and he replied with the "how old are you" comment.
I had no reply, he had me.
