Roger was trying not to laugh, Harry could tell. It wasn't a mean laugh, but it still made Harry feel...young. Which was weird, because it wasn't like Roger was so much older than him. Just a couple of years, and anyway Harry hadn't been young since he was eleven.
Forcing himself to take a breath, calm down he smiled back at Roger. He was acting like an idiot, and it was entirely unnecessary. "I wasn't actually heading anywhere. I was just...walking." Hopefully that sounded less lame than it really was.
Suddenly, he was reluctant to just go on his way. He hadn't realized until now that company was just what he wanted, and Roger was always great company. "I wouldn't mind company, if you weren't heading anywhere important."
