Ron shook his head as he pulled off his pants. "Harry, you don't even know him. We weren't even... boyfriends or anything anyway... just friends who... did stuff... sometimes." He reddened slightly, hiding it behind the shirt he was pulling off. "It ran its course. It's fine. Besides, that Williamson is pretty fit, isn't it? Think he'll shag his students?"
Now clad in only boxers and socks, Ron walked over to Harry and tugged on his shoulder a little. "Come on. Finish undressing so we can sleep already." He flopped down on the bed and looked up at Harry. "Assuming you can get your clothes off, and don't get trapped in your pants or something." He grinned, waiting, and not at all hoping for some good cuddles.
