Who Gives A Shit: Laundry Etiquette 101?

Another simple question: (if you live in an apt building) Do you think its rude to leave your laundry sitting in the washer/dryer? and/or Do you go ballistic when other people touch your shit in the laundry room?

That's it.

Again, answer in the comments (and feel free to go stealth anon if you want some prive).
