Intentionally Insulting Christmas Gift

This is a question about how to respond to a gift worse than nothing.

My nouveau riche inlaws palatial mansion has never been my favorite place to spend the holidays. In over 20 years of marriage I have gotten used to having absolutely nothing under the tree for me - the not-by-blood relative. (I say nothing except the gifts I buy for my kids to give me or what my husband and I have agreed to give each other)

Their tree is always overflowing with lavish gifts for the parents and siblings and children. This year however there was a gift that was actually accomplished the concept of 'worse than nothing'for me.

Instead of nothing, I was given a lively Christmas gift bag with rubber gloves, plastic sponges, dishwashing liquid and a scrubber. I contrast this to state of the art electronics, designer clothing, fablous jewelery given amongst themselves.

I didn't say a thing one way or another and should have just left the gift there or thrown it away there. Coulda shoulda woulda. These folks are shallow and self absorbed and I would like to do something to communicate that I need not ever darken their door again.

Would it be OK to send it back saying that I just can't accept such generosity and please give to someone else?

What I would really like to say can't be published. Any suggestions?
