How to talk to girls outside of school.?

I am a junior at high school and i can easily talk to girls in a school environment and get their number pretty quick.



But outside of school, i'm just plain boring. I dont know what to say. Any tips on what to say? should i talk about times i had with my friends that were funny? or should i talk about her and be interested in her?How to talk to girls outside of school.?
a conversation has to have a perfect balance of telling about urself and asking the other person about themselves. talk about things ur interested in, make jokes... email me or chat if your ever bored haha
