It's my mother's 60th birthday celebration this weekend, she has booked a house that sleeps 10 so all her children, plus partners and grandchildren can stay together. There is a meal booked Saturday at 3pm and a big picnic the next day. Dp has been invited to a party by a friend Saturday night from 6pm. He thinks I am being unreasonable in saying he can't go, says no one will miss him for a few hours and we live locally so physically he can do both. I think he is being unreasonable for thinking it's ok to leave my mother's bash! She's paid a lot of money so everyone can stay under one roof, it's obviously important to her we're all there.
