Most Helpful Guy
Yes! I always say the same thing: if a girl approaches a guy, she instantly wins like 1000 points. Girls don't tend to approach, so when a girl approaches I assume she's really interested in me.
And it's simple, just come up to me and say hi! You have a pretty smile, so take advantage of that; exploit that trait.

If I saw a guy and he smiles at me then I would approach otherwise I would stay away
