I was selling my friend an eighth, and we decided to meet up at a store parking lot in the back. As I get there (he is with 3 people), he hops in my car. About 10 seconds after that a vehicle pulls a couple spots to the right of me (he is parking further from the store). He pretty much stares at me and my friend in the car. We look away for a few seconds and look back and he is still watching us. About 10 seconds later we look over again and he reclined his seat back, and was still watching us. By this time I decided to get the fuck out, and to go meet at a different spot. I got the license plate of the car, and I got a friend who is a cop, so tomorrow he's gonna look up the plates and hopefully I can see if it is someone in the law enforcement area, or if it is some random bored dude. Am I just being paranoid?
