On a sunny afternoon was standing leaning against the railings on princes st, Edinburgh,waiting for a bus, and a young girls came and stood right beside me, for no reason, completely infringing my private space, I wasn't in the queue, at the time I assumed it was her trying to pick me up, but on balance she had to be a pro, never happened before or since, wish I had made a move. Before she came over, she had given me a serious stare. Remember I am 60, she was about 24.
