lol go for the 15 yr old, u obvously like her the most, so dont bother with the other 2, keep them as friends (aka backups if all else fails lol)

i met this new girl, and me and her would blaze together, and get really high out of my bong. everything would be kinda akward when we got back to my house. i would just start talking to her like one of my buddies, making jokes and being an idiiot, and she started to relax and get closer to me

so in short, your both nervous about what the other person thinks. so if u make the air less tense, its easier to open up and relax

hope this helps, post back when u know whats going on, i wanna hear about it
