What the hell is wrong with people?

Three nights ago someone threw a beer bottle at the back of Johns car while it was parked in the middle of the night. It was thrown so hard it shaddered the bottle into tiny peices, almost like sand. Some big chunks, including the ones held together by the lable, lodged themselves into the crease between the trunk of the car and the seal around it. Thankfully it did not break or crack the window.
Then night before last someone broke into my car. They tore through everything. Tossing it everywhere. They took the watch and bracelet Corey bought me that I was taking into the jewler to have resized. They took the first aide kit out of the trunk. They dumped everthing out of my "uh-oh" bag that I keep in my trunk incase we ever get stuck somewhere overnight due to weather, car trouble, whatever. They left stuff scattered in the berry bushes on the hillside across from us. The worst of it all ... they sat in the car smoking and then proceeded to put their butt out on the floor of my car. Burning the carpet and such.
So I ask again ... what the hell is wrong with people. They took two items, messed things up, pulled of some vandelizm, and stunk up my car. Why? Because they could!!!!!
All this while we were sleeping. We haven't lived here long enough to piss anyone off. And we don't have expensive cars. Now, everytime I walk out to my car I am going to be anxious, looking for damage or something.
JERKS !!!!!!!
