Boy Advice: Smile something to think about or give meaning?

Your friend is only trying to help, but let me tell you from personal experience that a smile does not go that long of a way. Yes it is good to smile at the guy you should never smile or break eye contact frequently but after the first five times of smiling it just becomes a confusing mess. You must also take into account that he will react based upon your smiles so if neither one of you ever speak you will just be left with a big question mark in your head. So yes smile a few times but after that if you get a positive response make a point of going over and at least saying hey. A little gesture goes a long way.
