Don't ever write texts for your buddies lol

My buddy meets some girl on Tinder that knows of him through mutual friends. She flat out says that she is super interested in him because he's in a band and she's a big fan of the music. He wants to pen pal it with her but I help him get her number and set up a date for next week instead.

Next night he finds her while we are out partying.  He manages to kick it with her all night, walks her to her dorm and instead of going for the pull he asks if they are still on for their date next week. He then proceeds to turn around and leave. WTF DUDE!!!!!
