I'm not really sure how to feel about this, I feel like maybe my mom has been trying to make me feel like my grandma doesn't care, but at the same time what if she just misplaced the card?
How would this make you feel?
The entire time I was growing up my mom would "invite" my grandparents to birthday parties, Christmas, thanksgiving, etc and they would never show up, if we went over there it was on her terms and we were not allowed to ask why they couldn't make it to our birthday or whatever.
If we got Christmas gifts from them my mom would make us throw them away after we left because according to her it was just dollar store crap anyways. On the off chance that they showed up out of the blue with no warning on our birthdays whatever, in the card was always money, we were made to give the money to my mom.
So basically in a nutshell my mom has always made sure we have as little contact with our grandparents as possible...
