I booked a lovely seaside restaurant to go to after a walk nearby. Told him the plan yesterday and he agreed. Wet here all morning but dried up by 2pm. I said let’s go in 15 min everyone get coats etc and be ready. He told my son he could call for a friend to go out and play - I said no you can’t as we are headed out. He then told my other son he could watch a program - again I said he we need to leave in about 15 min and he said he could still watch it. So son still watching program, husband still sat on sofa and basically there’s no point now. I’m quietly fuming!! AIBU?!
