I was driving out of a supermarket car park today and ahead of me a woman was reversing out of her space. She was quite a long way ahead of me so I continued driving mega slowly so she had time to get out and then stopped leaving stacks of room for her to finish reversing as she hadn't vacated the space by the time I got closer. She had a girl in the front of the car and a boy in the back, both of whom were shouting goodness knows what at me and making the Loser sign when I had done absolutely nothing wrong. As I followed them out of the car park the boy kept turning round to do the Loser thing. How can that woman allow/ encourage this kind of behaviour?
