I wish I knew how to make it okay! My sister is the same way with my kids- teens, now, for Christmas... nothing - no card, etc... same thing happened for my older son's graduation in June. She is on a tight budget but at least a card or phone call would be nice. But then when she tells me she is shopping for a gift for a friend - grrr. I just send my nephews gifts. Maybe one day she'll get it!
