Several weeks after our son began his freshman year at Alma College in Michigan, my husband and I decided to visit him. I was careful to call him a few days in advance to "warn" him that we would be coming. When we arrived at the dorm, however, I was taken aback by the disarray of his room. "Forgot we were coming, didn't you?" I teased.

"Are you kidding?" he replied, "Why else would I have bothered to clean?"
