I totally disagree. Yes, I have my own taste but I accept gifts graciously b/c of the thought and time/work, whatever went into the decision to give me something.
My MIL has the worst taste of anyone I've ever known!! Over the years she has given all of us absolutely nothing we would ever want or use and that includes my DH (her son) me, and our 3 kids.
We would never let her know b/c it gives her great joy to shop, wrap etc.
It doesn't matter in the long run. We'd rather see her happy. The stuff goes to Goodwill and places like that. She is none the wiser.
