The shy smile.
The nervous smile.
The 'you have to be kidding me' smile.
The 'I'm so glad you walked into the room' smile.
The sexy smile.
The great big toothy grin.
The 'it's threatening to turn into a belly laugh' smile.
The 'I'm up to something' smile.
The 'I'm so proud of you' smile.
There are so many more smiles than this in the world, all with their own unique magic. Even the polite 'please go away' smile is nice in it's own way. At least someone is trying to be nice to another instead of just telling them to '*$%~ off'
We all love those little rays of sunshine that even on the greyest day brighten your life. But I can't help feeling that bacteria could learn a something from the little ol' smile. It is the most contagious thing I have ever observed, one smile and a couple of seconds later it spreads to the next person and the next and the next. It's one thing I never mind catching though!
But if there isn't one around to catch and you haven't got a reason to smile, try faking it for a while...you never know, it might turn into a real smile and start a epidemic.
