1) You can walk up to a girl and say, "Hey girlfriend," but if you walk up to a boy and say, "Hey boyfriend," it kind of freaks him out.
2) I have reached the age where other women who don't know me but need to say something to me get my attention say, dear or ma'am. No more chica or sweetie for me.
3) I've also reached the age where apparently you're not supposed to laugh when other people fall down. I'm not sure when that transition happens, but I guess I passed that and no one told me.
