My mum lives by herself in a smallish flat, and for her birthday always has the family over for tea and cake. My mum has four children and each of them has between 2-3 children and now some of them have their own children. So although we're not a large family it can get quite crowded when everyone is there.
The tea and cakes is always served in the dining room which is where all the adults sit and the younger children usually play in the living room. The youngest are between 4-9.
My niece and nephew were sat at the dining room table, they are both aged 17 and 15 and were the first to arrive with my sister. When others started arriving it was made clear by some that they should give up their seats for the adults and be made to sit in the living room with the younger children. I'm in my early 20s and made to feel sometimes that I am not adult enough to be sat with the older adults.
Should they have given up their seats for the older adults?
I'm really of the opinion that they shouldn't have, but others in the family would clearly disagree.
