Could have put this in AIBU. Yesterday, ds came home from school with his ((white, logo-ed) school PE t-shirt under his shirt... spilt a bit of food down it so, as we have no tumble-drier, sent him to school today with a plain white t-shirt for PE.
When the time came for PE, the teacher said he wasn't allowed to join in as he didn't have the correct kit - so he had to just sit and watch. Am I over-reacting if I go into school tomorrow to complain about this?
