This happened on Christmas and I meant to post about it then, but got distracted and just remembered.
DH's mom and stepdad live several hundred miles away from us. For Christmas they stay with DH's oldest stepbrother and his family, who live about an hour's drive away from us. For Christmas this year we joined their family gathering. There were 14 people there, 11 adults and 3 children (the hosting stepbrother's 9- and 6-year-olds and my 2.5-year-old). There were 2 tables set up, one with 10 seats and one with 4. There were name cards telling us where to sit. I was seated at the 4-person table with the 3 children.
I didn't say anything to the hosts, but I was very offended by the arrangement. I understand that they couldn't just add a chair to the bigger table because there were only 10 chairs of the correct height (it was a high table), so the split had to be 10 and 4. But - why me? DD is old enough to eat without close supervision. If I were the hostess in that situation I would either take the 4th "kids' table" seat myself or just not divide tables based on age so no adult would end up at a table without any other adults. I would never stick just one adult guest at the kids' table, treating them like an afterthought whose inclusion in the adult celebration doesn't particularly matter.
FWIW, both DH and MIL offered to trade seats with me, but I declined because it's their family and they rarely get to spend time together.
So my questions: Am I being unreasonable? Would you be offended if you were me? Would you wonder if it was an intentional slight (I am leaning toward simple thoughtlessness)? Would you consider doing anything differently next year? How would you have divided the tables if you were hosting in this situation?
