DEAR ABBY: My adult daughter, "Suzie," spent the weekend at our home, bringing along her boyfriend of six months. This was "Liam's" first visit.I allowed them to share Suzie's old bedroom, which we have converted into a family office. We keep a large futon in there for my daughter when she comes to visit. I didn't make a big deal out of where Liam and Suzie should sleep because I didn't want to embarrass them, and I was sure there would be no "hanky-panky" because our bedroom is right across the hall.Well, I was wrong. In the middle of the night I was awakened by Suzie's squeals and moans. Fortunately, my husband is a sound sleeper. The next morning, while my husband was out on his daily run, I let the kids have it -- to the point of slapping Liam around a little. I told Suzie her actions were disrespectful and I was highly disappointed in her.Suzie and I are no longer speaking and I am miserable. Do you think I overreacted? Did I silently give permission for such behavior by allowing them to share the same futon? And did Liam really think it would be OK to have sex in my home? -- MISERABLE MOM IN WISCONSIN
