Ran into a random guy couple times on campus. He's very polite and always smiles at me and says hello to me first even though I don't know him. Yesterday, I ran into him unexpectedly again at subway (where he works). When he carefully made my food, he told me that I smelled good. is he flirting or is he's just being nice? Do guys compliments on girls about their smell if they are not attracted to them? What does it mean when he says you smell good?
