So I'm a 20 year old male and I spotted this pretty girl in college. I want to approach her but this is very hard because she always sits with friends. Another reason for this is that I maybe want to message her first but our college year consists out of 800 people so it'll look kind of stalky when I know her name and message her. I also just feel like i'd completely blush when I would go talk to her and I wouldn't even know what to say to her. I don't want to ask too many questions but on the other hand i want to keep the conversation going. WHAT TO DO???
