That's funny, it's also exactly what I say when I want to mess with her. I'm not a dentist yet, still have years left, which if anyone is wondering dental school sucks!
We have been together since 8th grade, last year right before her birthday I told her "You're getting old, I think my lease is up and I'm going to trade you in for a newer younger model..." Her reply without missing a beat was "You do realize I can get better than you and you definitely cannot get any better than me..."
