I smile to everybody. Always have and hopefully always will. A smile is a wonderful gift. It can be given infinitely and you never lose anything, in fact your smile grows. If you are having a particularly challenging day, a simple smile can help you break the funk.
The crap about protecting yourself and poker face is all BS. You will not lose a damn thing if you simply smile. You might even help complete strangers get through their day and there's a chance they could pass that smile onto another person. Life is not that bad. We can poker face, or smile at our experiences. One leads to more poker face and a gloomy existence, while the other is the path to happiness and helping others.
I love smiling at the grumpy locals, they don't know how to react. Most just pretend to ignore me but it breaks the stare. Once in awhile there's a person that doesn't take themselves and their drama so seriously and actually smile back.











But I question ChewDawg's sanity, so maybe I'm second.
