Quote: As far as the girlfriend thing..flirting I am not sure I know how to do that.
just smile, be up-beat. don't question whether or not he WANTs you there, he asked you there didn't he? be attentive, let him do the talking, follow his lead in conversations, let there be quiet moments don't rush to fill the void you may end up missing out on what he would say or do to fill it. be appreciative, say thank you for the smallest of things.
and most importantly and probably the hardest. RELAX and enjoy YOURSELF!!
