I have heard different advice about smiling when approaching a set. Some people say that you should have an expressionless face when approaching a set until the girl does something to earn your smile. This is somewhat consistent with the indirect approach, because a smile can show interest. Other people say you should smile when approaching, because the set will open much easier.
I have seen members of the community approach sets both ways. Vector, for example, has a very easy, natural smile and people respond to him. When he is standing there smiling it is like he is already a part of their group. I have seen other people approach with a somewhat serious look, creating tension, and then relieving the tension by delivering a funny line with a wry smile.
I want your oppinions because I am personally invested in this. In fact, I am financially invested, but I'll get to that. I have a dry sense of humor. When I had a larger social network, I could work the fringes of a party, for instance, and build rapport with people one at a time by making them laugh. That has always been my personality, although that can certainly change, and that is my intent. In addition, I used to have jacked up teeth. Girls who already knew me have told me that my smile was "cute," but I never liked it. So I would hide my smile. I was definitely self-conscious about it.
Now I have a $13k smile (still paying for it, of course). I should be smiling like the Cheshire Cat. I'd like to have a natural smile. However, when I'm in the field, I'm afraid that it will come across as unnatural or incongruent.
So, do you smile when approaching? If so, is that something you do naturally, or did you have to teach yourself to smile more?
