For themselves on my birthday? I don't expect them to fork out on my dinner or my dh/dc. But its a 'milestone' birthday and I don't think it's fair to expect me to pay for themselves and their families.
Attending are myself, DD, DH.
My DMis bringing 2 DBros and DGM
My DF is bringing DSM, 2DBros and 1DSis.
They suggested going for dinner to celebrate, and now they've both said they're unwilling to pay. It's been booked for months and they've told me they don't want to pay when it's only 2 weeks away.
