DEAR ABBY: My wife and I have the same argument every year or so. It's about dancing with other people when we're out for the evening. I feel that "grinding" is sexual and that it's inappropriate for someone in a relationship to do it with anyone else.
I made my sentiments clear to her when we first started dating, but it seems that about every year when we are out, she'll start dancing with some guy in a very provocative manner. I'll get unhappy about it, but when I confront her, she gets angry with me and says that it means I don't trust her. I trust that she's not going to go off and sleep with some random guy, but I feel it is wrong because she knows how I feel about it. How can I get her to see it my way? -- PRINCIPLED IN SAN DIEGO
DEAR PRINCIPLED: She already knows it upsets you, so try this. Get up, join her and her partner on the dance floor, and start doing the "sandwich." And make sure that the person in the middle is YOU.
