A little boy came up to his mother in the kitchen one evening while she was fixing supper, and he handed her a piece of paper that he had been writing on. After his Mom dried her hands on an apron, she read it, and this is what it said:

For cutting the grass: $5.00
For cleaning up my room this week: $1.00
For going to the store for you: .50
Baby-sitting my kid brother while you went shopping: .25
Taking out the garbage: $1.00
For getting a good report card: $5.00
For cleaning up and raking the yard: $2.00

Total owed: $14.75

Well, his mother looked at him standing there, thought a few moments then picked up the pen, turned over the paper he'd written on and wrote:

For the nine months I carried you while you were growing inside me: No Charge.
For all the nights that I've sat up with you, doctored and prayed for you: No Charge.
For all the meals, snacks and drinks you've consumed over the years: No Charge.
For all the trying times, and all the tears that you've caused through the years: No Charge.
For the toys, clothes, and even wiping your nose: No Charge.

Son, when you add it up, the cost of my love is: No Charge.

When the boy finished reading what his mother had written, there were big tears in his eyes, and he looked straight at his mother and said, "Mom, I sure do love you". And then he took the pen and in great big letters he wrote:

"PAID IN FULL"
