So basically there is this girl in a class that I take and I think she is super duper pretty. I haven't really spoken to her though because I lowkey go mute for some mysterious reason. Would it even be appropriate to just walk up and ask her out, or should I like try having a convo with her first? I have gotten varied answers from family and friends but I need more convincing. Also I have a prom during the weekend so idk if its to late to ask her or what. HELP ME
