Would you have been more pee-ed off if she had rung the night before and said she couldn't look after DS? You don't have to suck it up but you might have to find other care for your son.
No I wouldnt have, things come up, I totally get that, what bugs me is that she knows it is something that worries me and she chooses NOT to tell me so that I wont make alternative arrangements KWIM?
She doesnt give me the option of making a choice.
