I think, the when who say "thank you" I become happy. So, giving is happiness for me! = I feel happier when someone says a simple "thank you," so giving is a form of happiness for me.

"There is more happiness in giving than there is in receiving."
-Acts 20:35-

Congratulations on your marriage!!!

“This is at last bone of my bones And flesh of my flesh."
