Primary athletics carnival is a "compulsory school day" and held off site. A lot of parents go to watch, but I really don't want to. DS2 will spend his day sitting outside watching other people do their thing (he is 11 and totally non-sporty); I don't really see what value I add by spending my day there doing the same. If he was actually participating in events it would be different.
By Thursday I will have spent two mornings at school this week reading/scribing for senior exams, and on Friday I will spend my usual weekly hour running a literacy programme with kids who need help. I'm happy to do this but I have other stuff at home that I need to get on with as well and I'm not feeling particularly well at the moment so sitting in the cold for 5 hours (it's nearly Winter here) is totally unappealing. DS2 wants me to "be there" and there is no real reason why I can't be - would I be the meanest mummy in history to not go?
