Harry shivered, remembering countless fire safety classes when he was in Muggle school and realising they had none....
"Protection would be a good idea. I'd like to learn some of those spells myself. I only know them for people, things and, um, large areas."

"I'm free tomorrow...." he said with mock casualness, knowing he was being a girl's blouse about it, but wanting the house protected anyway. There were too many precious people in it now to risk something as simple as a fire taking them.
