What are good signs indicating a girl likes a guy on a casual situation??

Question

Not when they are together on a date, but in a casual normal environment.

Answer 1

Well, the girl may try and talk to you a bit more than anybody else, or she may be a bit embarrassed and blush if she's shy. In order for her to loosen up a bit, because she's bound to feel a bit nervous, smile and crack a joke or something.

Answer 2

walking next to you flirting giggling whispering wid her friends
