My husband's 98 year old grandfather refuses to use a cane because canes are for old people and he's not old. =)
Maybe this should just be the thread of people who are glad not to be pimply-faced, awkward teenagers anymore. But who still write for teens. Just use "old" as a synonym for "not a teenager anymore."
(I don't write for teens, but I thought this was an amusing thread and stopped by. *waves*)
Of course, I'll stay away from the question-- what is SO bad about being old, anyway? You couldn't PAY me to be a teenager again. I'm 28. I'm looking forward to getting older.
