He has form for this but this one is a new level! There is a school trip which is above my budget. Usually it's not worth asking for anything as "I give your mum money for you blah blah" so, foolishly, I do.
Child returns with message that he will pay half of trip if I change our arrangement to 50:50 so that he doesn't have to give me money. This verbatim from child!
Never mind, I'll use my savings...
