Vengeance

Last night someone decided it was going to be fun to slash all four tires on my car. At first, when we found it i was really angry, then i was sad, then when i called the insurance company i was pissed. After a while i was resigned to the fact that it was going to cost a bunch of money we don't have. My wife had mentioned vengeance, at the time i said i just want the guilty party to pay for the new tires and tow truck bill. After a few more hours i decided i wanted to hang the jerks by their pinkie toes from a very tall tree. Now i just want to get past it and make sure it doesn't happen again. But i will continue to wonder why would someone do something so hurtful? How does one not get paranoid that it will happen again?
