* Not to beat the Christmas decoration bit to death, but anyone who still has their Christmas decorations up come Valentines Day is totally tacky!
* Re-gifting, if you don't want it just give the darn thing away please, don't wrap it as a gift, just hand it to someone.
* Selling used socks, undies and bras at a yard sale (yes, I saw this done) YUCK! and double YUCK!
* Telling someone sho is not very very very close to you about your bodily functions. Can we all say TMI!?
* Driving a Humvee when you don't live in the desert or the outback. I can't see any reason for this except to show everyone that you can afford a Humvee. It's not like you need to dodge landmines or climb mountains in suburbia.
