Be bold and initiate a short chat.
Watch for signs of flirting.
Check for random hugs, reserved mostly for you.
Take notice if she "accidentally" bumps into you more often than what you'd consider the usual.
Observe the way in which she looks at you.
Look at her friends. If you see most of her friends glancing back at you and smiling or giggling,
this probably means that she has told her friends about you and they're "in the know".
