If a guy gets this mischievous glint in his eye?

[Anonymous]

Over simple stuff, like if you're in awe of something, (like this building), he'll notice it all amused and then tell you about how it was made.

Or, like, if you're scared of dogs, he'll eye the dog thinking something, amused.

Does he like you?

He's paying attention to the things you say. He's probably interested in you.
