Why do I worry about things like this. I'll give an example. My DS is leaving primary school now next week (not England).
Obviously, due to COVID things have been all over the place the last few months and where we are the children haven't returned to school so won't be back before they leave. The school couldn't offer the usual leavers photo package so another parent organised a parent of a child in another year group to take some photos in a local park.
What you have to do is arrange you kids into friendship groups and then contact the photographer for a time slot. She'll then take an individual and group photo.
For some reason I've got myself all worked up about how the groups will work out and what if some kids are left out and don't get asked to be part of a group. My DS is sorted, but he's a popular kid who could fall into lots of groups but I'm panicking that this isn't going to work out and some kids are going to turn up alone and realise all the other kids have been matched up in groups. Please tell me this isn't my worry and I'm overthinking it?
