From my friend: she lives in a townhouse complex with limited parking. each group of homes is on a circle, and each unit has ONE assigned space, and the rest are open to anyone, residents, visitors, etc. She came home from work, saw one open spot, and took it. Neighbor was sitting in the lot, in his truck, but no blinker on or anything. She parks, he gets out and screams at her, she yells back. Apparently she was supposed to divine from him simply sitting there he was planning on parking there.
He's now parked behind her car, blocking her in. I told her a. call the police non-emergency line or b. if he's blocking her in, he may be blocking other cars, and someone may accidentally hit him (oops). or c. he presumably has to work tomorrow, and will have to move it then. problem solved.
