I've not lived with my parents for years, I live with my partner and have done for around 2 1/2 years and alone before that.
We send out Christmas cards to the usual people, family, friends, family friends yet almost never recieve one back to us. I am always included on my parents cards, which I never even see!
I know people have a lot to write, it's not that they didn't send me one, it's that they still treat me like a child.... When comes the point where you stop writing "parent, parent, grown up children" on cards?
First world problem, I know...
