which is the greatest good thing you have done in your life??

Just a week ago there was a family, a mother and two little girls standing in the medium in a shopping distric in my town. The mother held a sign that said Family in need of help, food or money. I immediately went to the grocery store and bough the family 4 bags of food. I took it to the woman and she cried like it was the greatest thing ever. I started bawling to. It was a great experience to help someone who was truly in need.
