Knock, knock. They're heeeere. When someone calls to tell me they're coming to town, I immediately put it on my calendar, look for fun things to do, and make dinner reservations. Since I'm fortunate enough to have a guest room, I offer it up whenever I can to close friends and family. On the opposite end of the spectrum are folks like my dad, who can't handle hosting guests or even being a visitor himself. A hotel down the street suits him just fine — it has ice buckets and he can run around in his boxers without fear of flashing someone. I, however, like to leave my front door open and fresh pressed linens. What are your thoughts on hosting house guests?
