okay number 1--i do that, but everyone messes it up. i fight fixing it so i'll seem not so uptight. (there was an episode of Friends where Monica did this. and i, like Monica, chase people around at my house with coasters)
and number 2---i do that too. well slightly differently...from left to right my closet is like this: short sleeve shirts organized by color, long sleeve shirts organized by color, dresses, skirts, pants. nothing wrong with being organized!
I don't chase anyone around with coasters, but I am definitely an advocate for coaster usage. And for those who pick on me for being organized, I can find everything in my room in five seconds. It's a time saver. Haha.
