No one needs a smile as much as the person who fails to give one.

I try to remember this every time I smile or say 'hello' to the dark-haired man that I often pass in my neighborhood. He fails to reciprocate every time, even when we found his diabetic kit and wallet in the middle of the street and rushed to find him. Husband calls him 'my buddy' and it's all I can do not to smile at him.
