This sounds really weird but I’ve had a few encounters with this school mum now and every time I’ve seen him it happens. Few times outside the school gates and one time in a shop near the school. She seems to be quite loud and ‘out there’. Anyway, she will just be walking normally and then when she sees me she will purposefully come towards me and into my path and block me walking and I have to go around and then she said ‘oh sorry’ with a laugh in her voice. First time it happened I just thought nothing of it but it keeps happening.
