Just wanted to share something. I've complained for a long time about my SD. But, amazingly, for my birthday recently, she sent me a gift. I almost fell over from a heart attack.
I do have to recognize that in a few respects, she is a better person than I am. She went from not acknowledging my birthday when she was very young, to giving me a card during her adolescence/teen years, to calling me and sending me a card (after she moved out), to now including a gift in the card. I've never once got her a birthday gift, I never call her, and I just sign the card my wife gets.
This is not to say that things are rosy. I'm still dreading the holidays. But I wanted to share how life can throw you for a loop and counter your notions about someone. And that people can and do change.
