I have definitely been accosted by the smile police too LOL. Sometimes, if I know I'm in a situation where people really need me to smile, but I don't feel like it, I'll actually ask someone if they could tell me about something fun. I often try to hold onto genuine smiles to make them last longer. Sometimes I just laugh at myself, or if I meeting new people, I try to just focus on the pleasure of meeting someone new. It's nice that someone wants to get to know me, or, here's a chance to connect with someone. It's hard sometimes though when I am networking or at a tradeshow, and after a while, I really don't care about meeting new people anymore.
I agree with others on here; there are way too many completely fake smiles to go along with the fake people. Smiles have no meaning by themselves, because you don't really know why the person is smiling, as I've just proven above. Still, I know that a nice smile sets a nice tone for the conversation. In customer service and retail and advertising, people of come to expect the smiles and cheerful voices, even when they are very obviously fake. In those situations, I have found that it is better to try a little practiced, professional cheer if I can muster it.
Plenty of people practice speaking in front of the mirror, and part of it is so they can see their own smiles and body language and such.
When I told my friend how I feel about the smile police after I read this thread, he said I sounded like Holden from Catcher in the Rye. I like that, since Holden is funny and genuine, even if he does need some perspective.
