Do U think U should get ur MIL a gift for Christmas when she's been bad this year. I mean she meddle into one?

of her son's marriage and almost broke them up. She acts like my 23mth old daughter (her grandkid) like she's stupid or something. Just b/c she can speak clearly or talk like an adult to her. She made many many bad decision to where causes friction in other people lives. I feel she doesn't deserve a gift. Plus, they decided to get only the kids gift since she isn't working probably can't afford many gifts this year. I mean we already gave them a free TV, home theatre system with 5 disc CD changer, and free over sized speakers(even though we wanted $50 for everything) but I don't think they can afford to give us that. So we just decided just to give it to them for nothing. What would u do?
