I hate people who do things like this, makes me so angry! why ruin people's property? people work hard for what they have and it takes a horrible person to ruin that for someone.
My friend went through a similar thing last year. There are no drive ways to any of the houses on her street so everyone parks on the road outside their house, there are usually around 20 odd cars parked in the street at one time. Some moron went down the street and smashed the drivers side window on every single car in that street, what sort of people do things like this? idiots!
