Severus found himself enjoying his discussion with Harry. They talked about books, sports -- Muggle and Wizard -- and touched lightly on their personal lives.
At one point, when Harry was heating a casserole for dinner, Severus wandered about the solarium.
"You have one window with some frost on the inside," Severus said.
"I keep meaning to get that fixed!" Harry sighed. "It needs caulking around the glass, but I never seem to remember to call someone during the day."
"It's not hard," Severus replied. "You can I could probably do that in an afternoon."
"You'd help?" Harry asked, looking surprised.
"Certainly," Severus promised.
