I think she likes you, bro.

If you ever get in awkward silence again, ask random questions.

Like:
What's your favourite vegetable?
If you could be any animal, which? And why?

Stuff like that. She probably either laugh at the random-ness or say "that's a random question" and then answer it.

BOOM! Conversation started.

Oh and don't be too shy to ask her out. If you don't, someone else probably will. It's happened waaay too many times for me.
Oh, and if you get friendzoned, then it's been valuable practice.

Good luck dude.

Oh holy moly, that was hilarious.
