My DSS is 25. For the past couple of years he hasn't really kept in touch much, come to visit us, and hasn't sent our dc cards or anything on their birthday. DC are 10 and 14.
WWYD? It's not about the presents; it's about our/our dc's relationship with him. We used to see him regularly and he remembered their birthdays, etc.
AIBU to feel frustrated and upset? I know he has his own life now but that doesn't mean forgetting family, does it?
Would we BU to forget his birthday? Or say something like, 'Since you're not bothering sending gifts or cards now, we won't buy you anything for your birthday?'
