Look at this example of a body paragraph about learning to be kind:

when working at the grocery store, one of the lessons i learned was to be kind to people. the store always emphasized personal relationships with customers, but i was never really comfortable talking to others. i remember one day i was walking down the baby aisle and saw a woman with three kids trying to pick up some baby food she had spilled. i quickly her and then got some cookies from the bakery for her children. the gratitude in her eyes for that simple act of kindness touched my heart.
