What can we do on a friday night, with three girls and two guys (we're all 15)?

make a fire or something and roast marshmallows. talk. run around play capture the flag i no this is kinda kidish stuff but like u could have like water gun fights water balloon fights.basically do stuff that u all like like lets say the guys like running.and the girls like water and screaming.then water ballon fights are a ok way to combine what every1 wants to do
