Never tell a girl you like her unless you're completely sure and its been a long time. Most of the time they'll tell you first. Play it cool ;D
that is so wrong it's scary
girls don't want to feel like a predator.
example: i was at a party, chilling on the couch with one of my friends. he is nuts, so he jumps up and screams "RUMPELSTILTSKIN!" and proceeds to walk into the center of the room, take his shirt off, bite a hole in the can, and drink the entire beer. i was left sitting there very confused, and then this girl sat down next to me. she glances at me, then when i look at her she looks away. i kept looking at her, giving a smile to see what she'd do. she didn't do anything, i had to open conversation with her. if i didn't then nothing woulda happened.
girls don't want to actually be the ones chasing. they will do absolutely everything they can except for actually chase you.
