I'm a freshman in college and I was at dinner with a female friend from high school and some girls from her dorm. One of them sitting next to me was showing some serious IOIs like touching my arm and laughing really hard at anything I said. She was pretty cute but when she left early I pussied out/didn't want to ask right in front of like 6 other freshman girls. Later that night I just got her number from my friend from high school. Was this a weak move? Any advice?
