things people that you live with do that really piss you off.
using up everything but a drop of something eg. milk, and then putting it back in the fridge.
scraping out peanut butter from the middle of the jar but not the outside so it looks like it's a full jar.
never cleaning up after themselves and generally leaving a mess and chaos behind them.
going into my room and taking my stuff without asking.
etc.
everyone else?
