I love this thread- you're solving my dilemnas. I told family I wasn't chipping in for gifts for Mom and Dad anymore. Not buying anything. If you buy for dad he puts it in the closet and doesn't wear it, then gives it away. Mom will wear it once and give it away (you don't know how TICKED OFF I was when my sister was wearing a dress I bought my Mom- quite expensive and she looked great in it!)
So, I'm saving my money and not buying anything. I don't have in-laws, they exist- but to them, I don't. I wouldn't buy them coal because that has value. I would put some of the stinkiest poo I could find in a plastic bag and wrap it nicely. After 26 years, they still refuse to acknowledge my existence (just got the kids straightened out that Dad isn't going home to Mom anytime soon- yes, she's still waiting for him).
Aw, family. thank God I have you guys for "sisters."
