Dear Amy: Recently, we hosted a couple as weekend guests. The wife and my wife were friends in college. I picked them up at the airport on Friday afternoon and brought them to our house, showed them to the guest room, and we all sat down to the dinner that my wife had prepared. On Saturday, after breakfast they spent the day with some friends of theirs, and returned to our house for another homecooked meal. On Sunday, our guests suggested that we go to a nice restaurant for dinner, which we did.
