“Some people are too tired to give you a smile. Give them one of yours, as none needs a smile so much as he who has no more to give.”
“If someone is too tired to give you a smile, leave one of your own, because no one needs a smile as much as those who have none to give.”
“If you see someone without a smile give them yours.”
“He who gives money gives some, he who gives time gives more, and he who gives of himself gives all.”
“If you only have one smile in you, give it to the people you love.”
“...Some people hurt so much they can't take what they need, even when someone wants to give it to them. (106)”
