DD, 14, is going on a school residential to Europe in October half term. She came home, asked if she could go and applied for a place. Normally during half term she would spend some time with her father but obviously can't, it's not something arranged as part of a court order just an ad-hoc thing.
Now he's kicking off saying that it is more important that she spends time with him than goes off with her friends on a school jolly and wants her to pull out of the trip. She is saying that he's being a twat because he hasn't seen her at all in the summer holidays because he went away for three weeks and was busy the other three (he's a teacher).
