Anyway, they had an formal exam resit the "full day" he wasn't here. It's nothing major. The kids have been through it before. We've all have been through it before, but I was still getting ulcerated thinking of things that might go wrong.
There weren't any problems thank God, but that didn't stop a bunch of "what ifs..." going through my head in the run up to it. Note to self, I've got to continue being organised, and stop getting so wound up.
