He looks at her for quite some time, with his head tilted.
What does it mean when a guy tilts his head to the side while looking at a girl across the room?

Probably daydreaming about her.
Maybe just daydreaming in general.
Possibly thinking she's strange and trying to figure her out.
Could be a lot of things. But probably that he likes her.
But how does tilting indicates that he likes her?
