You can go to prison for that! If you mean flirting and gaining her interest then stop the play acting and go up and introduce yourself to her and ask her out. Don't think for a minute that most young women want to hop in the sack with a guy immediately and would like to get to know him a little first.
Chat with our AI personalities
First, smile at her and see if she smiles back. If she does, then that is a good sign, and you should go over and introduce yourself/say hi. Have a brief chat, and then go. The next time you see her, you will have an excuse to speak to her, so go over and talk. Us girls like it when boys compliment us and chat. Hope it goes well and good luck!
