Smile

In the morning today i was coming to work and suddenly i had this urge to just smile. I tried, i tried to just smile for no reason at all. I tried and i tried and i ended up with something in between an amused frown and a silly grin. Why? I looked about me at the people in the other cars and i saw the same thing everywhere, frowns, people ion deep thought, or just blank looks. They say it takes fewer facial muscles to smile than it takes to frown and even then why are people so inclined towards doing more worn than is required? I decided to give a smile to everyone who looked my way. I did give smiles. I got smiles back. :) My day suddenly got better, for NO REASON AT ALL!! :)
