I came across this lovely piece of inscription. I found it worth a moment to spare to look at. I smiled and rolled along . A smile goes a long way. Take it with you, and it may just save you loads of  self explanation ; when you're late for a meeting, when you trip over a ramp in the park and  you feel the whole world is watching you ,when you forget to cash in with the cashier over the counter and you are  reminded to pay the bill, or when you are simply cross with someone. So always take a smile, or at least back pack it if you have trouble wearing it all day :)
