I’m probably going to be flamed a bit here 
I am 40. Most of my friends had children in the 33-37 age bracket so the youngest are now 3/4ish.
The thing is this. I’ve bought presents and cards and made a fuss and liked photos on Facebook. Now it’s my turn and nothing.
I know it’s a bit petty but it does make me sad.
AIBU to think they should perhaps feign interest, given I did for them?
