I always park on the same street for work because its in a quiet area and you don't have to have a permit, so I save a lot of money and its only a 10 minute walk from work.
There is a row of flats on the street (only about 8 in total and only 2 storeys high)
Last week after I finished work I got in my car and was sat texting, I then had the feeling I was being watched. I looked to my side and there was an old lady on her balcony giving me the most evil look imaginable. I was slightly creeped out so I started up the engine to go, looked out the window again and she was sticking her finger up at me.
Confused, I wound down the window and asked what her problem was, to which she ignored me and carried on doing it.
Maybe she's annoyed that I park there and don't live on that street, however its a really quiet street and hardly any cars and so I don't think I'm ever preventing someone from parking on there. Also the flats have their own private parking so I'm definitely not taking her space.
