Well, this is not quite what I expected my next story to be like…just a little drabble, really. Set sometime after DH, mostly canon, except for one character who managed to survive. Enjoy :)
A Chance Encounter
"I don't begrudge you for how you acted, you know." Harry said casually—even easily—to the man who had stepped into the international floo line behind him. "I'm not sure if you regret it," he gave a small shrug, "you probably haven't even thought about it." He turned around to walk forward the few steps the line had shuffled forward. A minute later, he turned around again. "I don't know if you're still teaching, or tutoring, or anything-"
"I have an apprentice who will soon be moving on to start his own business—not that it's of any interest to you."
"Oh" Harry fell silent. He glanced up at the tall, foreboding man in line behind him before continuing. "Before my first class with you, I couldn't wait to learn about potions, you know," he said conversationally. "I thought it would be fun, and don't give me that look! I was prepared to work, but I was also expecting it to be enjoyable...like how you enjoy it." Harry trailed off for a moment before giving a rueful smile. "I don't suppose it matters much now, but if you ever teach kids again, you may want to consider that."
"Sir, Excuse me Sir, the floo on the end is open—Oh! You're Harry Potter!" An attendant gushed. "Let me walk you down there, Mr. Potter, and on behalf of Primary International Floo Travel, I would like to thank you for..."
And Harry walked off, smiling politely, if not a little uncomfortably, leaving a very shocked Snape in line behind him.
