Smile at a stranger today!

Isn't it easy to keep your head down and walk without noticing those around us?  I dare you to keep your head high today and smile at a stranger that passes by.  You never know when that little big of positive energy will have a domino effect - and impact many other people.  That stranger will smile back at you, someone else will see it, it will cause them to smile... and so on and so forth.  Start the trend.  I dare you!   Go on now.  Someone could be passing you by RIGHT NOW!
