I notice every year that my mother sends Christmas cards in the mail. It's usually to her siblings and their parents. She usually gets cards too in the mail.
I get it's a nice tradition but I thought about this. My mother and her family of origin/siblings - they never make time for each other. They don't see each other from one end of the year to the next. Excuses are made when it comes to any meet ups. They only see each other really now at funerals. One funeral was in 2010 and then another 11 years after that. Her siblings are all living in the same country and to be honest there's no excuse for not meeting up.
I mean like, why bother sending Christmas cards like this? I know it's a nice tradition but it's a bit pointless at this stage. Sending cards to and from people that don't make any effort to see each other - it's crazy. How about sending cards to people who are genuinely in your life.
