It's chaos outside our primary school at home time with groups of parents standing around the gate but I understand that you need to wait somewhere and we're all just doing our best.
However what really gets my goat are the parents, with children collected, standing chatting on the fairly narrow pavements immediately next to the school so that nobody else can pass. Every afternoon I've had to step out onto the road with a 5yo DS in order to pass people. It's ordinarily not a busy road but it becomes so at school pickup.
There's just no need, if you want to chat why not you stand in the road and leave the pavement for people who just want to get home safely, or go further away to an area where you can stop safely.
