sorry its long but i really need your help asap.
basically me and a couple of friends got into some trouble with the police on halloween for using fireworks in the park. about an hour later that night me and 2 of the friends decided to take a walk back through that park on our way home. as we were walking down the path there was a group of 3 girls and 1 guy who were sitting at the benches. as we were passing them one of my friends jokingly said "now that's how you run from the police" (because they saw us before). the girls showed some good indicators of interest, like one immediately approached me and began showing me pictures of her friends on her phone before i could even say anything. we then hung around for about 20 minutes before we decided it was time to leave. just as we were leaving i thought i might as well get her number seeing as no-one else in my group seemed to have tried so i did and she gave it to me (and so did the guy they were with because i figured he could be a lead into more girls and parties and such seeing as he was hanging out with girls) after getting her number i told her i would text her so that she could save my number. after leaving the group i texted her simply saying "save my number - william" (as i didnt want to seem too happy but appear cool and casual). she then replied saying "cooool x". the only problem is that this was on the final day of my unlimited texts (october 31st) and now ive finally got texts again but its been 2 whole (15 days) weeks since i met her and i dont know what to text her to start a good conversation. please help! :
and btw the police thing was all just innocent fun, ive never been in trouble with the police and i do not think i am "cool" for doing so.
