Well, yes. An ogre. In the middle of a forest inside a modern city.
Harry wondered if he was dreaming.
The ogre seemed to be grumping and whining to itself rather than mounting an attack, so Harry went closer. He tried talking to it, asking it about the princess. The ogre just growled and grumbled, looking pained.
Maybe it's just hungry? Harry had bought a Snickers bar at the deli, and it was in his jacket. He slowly reached out and placed the candy bar on a rock between himself and the ogre.
The ogre snatched it up and ate it, wrapper and all, and seemed thoroughly pleased. Harry waited a few minutes, and then tried asking about the princess again. And again. The monster no longer grumbled, but it didn't appear to have anything else to say.
Probably doesn't even speak real language, Harry thought. He gave a half-hearted wave and slowly turned around to start walking home. What a waste of time!
(Indeed, it was. Try again?)
