I still live with my parents and today arriving home from work I see a letter that doesn't contain a return address. So I open it and find some threats to me and my parents because I start my car and leave for work between 4:30 and 5:30 on some mornings. I don't rev it or speed in our neighborhood though either. My car can be pretty loud, with a Vortech/Magnapacks and a OR X pipe. Said person stated I "should be checking my tires each day" and called my parents and myself, **** suckers and pricks. The writer also stated the police will soon be called on me.. I don't particularly know who is sending them, but I will hold onto the letter in case something does happen. I wonder what the neighbor would say if I got a bike and rode that to work in the morning! Is there anything else I should do to protect myself from said asshat?
