..... I often do.
I find it hard not to because I feel guilty.
This year DP bought a present for my brothers girlfriends DD who is in her early 20's. She's often rude to us, never buys us a gift and doesn't even thank us. (Neither do my nieces and nephews).
I said to DP not to get brothers gf DD a present this year but it's done now.
If you were buying for someone who never got you anything, would you stop?
I know it's not about giving to receive. But I do wonder about effort. Or even just a simple 'thank you'.
