Every year I send Christmas cards to people on my Christmas card list. Apart from relatives and good friends the people I send cards to include my best friend from high school, who I still see from time to time when I visit my hometown, friends of my parents, old neighbours, acquaintances and people I see only casually.
A few of these people never send us a card back, or they only send us a card after we send them a card first.
DH thinks it's a waste of time and money to keep sending cards to people who don't make an effort with us. He also doesn't see why I keep sending cards to my best friend from school (I also send her birthday cards). I'm late 40s, she's 50.
We were friends throughout all of secondary school and we were in the same class. We also used to go to each other's houses so we knew each other's parents and immediate family. This year I sent her and her partner a Christmas card but we haven't received a card back (my card was sent rather late so they may have only received it on Christmas Eve).
I keep sending the cards because I think it's a friendly thing to do. I actually enjoy sending people cards.
IS DH BU?
