When my roommate, Nikhil, announced he was going to Mauritius for three months and asked if I could take care of his dog, I thought immediately of body heat. A 70-pound German shepherd throws off a lot of warmth, and I sleep in a poorly insulated room.
“Can he sleep in the bed?” I asked.
“He’s not really supposed to, but…”
“Done,” I said. “When do you leave?”
