My parents called and asked if I wanted to do dinner with the family for my birthday. I said yes. It was a car pool so my dad picked up everyone in their minivan (me, my two brothers and their wives). I was picked up first and ended up sitting in the very back of the van to make it easier for the others to get in. For the last pick-up, my brother and his wife jumped into the van's middle seat and said hi to everyone else but didn't even acknowledge me, let alone say Happy Birthday. When we got to the restaurant, we were an odd number (seven) and they sat us at a table for six and brought over a chair to squeeze me in at the end of the table. It was impersonal and offensive and I was largely ignored by my family the entire time. Should I confront them or just cut them off?
