I Am About To Come The Worst Roommate Ever

So some of you may or may not know but I have been experiencing some problems with roommates and this is the reason I am moving once my contract is up. I think today as put me over the edge, or at least it is starting to.
Just this school year I have had 4 movies stolen, the beaters on my brand new hand mixer bent because they were put in the dishwasher wrong, my seasonings and other staples used up and not replaced (I didn't use them up) and those are just the big things that stick out in my mind.
The youngest person in my apartment is 21 so this means we are all adults and should all act like adults. With that being sad today I went to make myself some dinner and then went to grab one of my blue bowls (now I have had these blue bowls since I graduated high school) to put my pasta in there are none in the dish cupboard so I open up the dish washer and there are none in the dish washer, none in the sink and none in the refrigerator. Now how do 4 bowls get up an walk away especially when I remember using one of them 2 days ago. I know that I am moving out at the end of May and that all the dishes in the kitchen are mine with the exception of a few things but that doesn't give you the right to send my stuff home with your friends or hide my stuff in your room so that once I move out you have dishes. When I discovered this I started doing inventory and I am missing at least 4 bowls, 2 plates, tons of spoons, and a few pans. Also while I was going through the cupboards most of my dishes were dirty so now I get to be the person to clean them. Last night they had a party and my games are all over the living room. If they can't respect me I sure the heck ain't going to respect them and my stuff will no longer be used with out my permission including my dishes. Oh well too bad so sad they should have thought of that before they ticked me off. For those of you who know me know that it takes a lot to make me mad. I have tried to respect them and be nice but it is all over.
