Pleasantness = Tzedakah!

Hi,

"One should greet every person with a pleasant expression.

"This teaches that a person who gives another person all of the great gifts in the world, but with a depressed expression, is as though he had not given anything.

"However, a person who greets another person with a pleasant expression - even without giving him anything [tangible] at all - is as though he had given the other person all of the great gifts in the world."

(Avot deRabbi Natan 13:4)

Have a great day,
Mordechai
