"A smile Costs you nothing and your surrounding circumstances should not determine your response to life."
Sometimes when am not in a good mood or when something bad happens and I walk sullenly down the road, I always have someone who tells me.. "Smile dear, you don't know who's day you'll make just by doing that"
And sometimes when I walk down the road and see someone with the same sullen expression etched on their faces, I try to say a word of encouragement too. It might not suddenly make their problems disappear but it can put a smile on their faces.
Make someone smile today
