A little boy approached his mother in the living room, when she rested in her room, she thought she needed money to buy things in her school and an idea occurred to her, and she wrote on a sheet to her mother a note that said: take out the trash you pay me 2 $, for cleaning my room weekly 1. $, for doing my homework without help 3 $, for bathing without help 2 $: total pay me: 8 $. His mother looked at him from head to foot and remembering, she takes another sheet and I write: For the nine months that I took you while you were growing inside, had no value at all, at night when you got sick with fever and I took care of you, had no value at all. For celebrating your birthdays, making the best gifts, your favorite desserts, and everything you did to make yourself happy, had no value at all, and at the end of the letter she said "Son, when you add all that I mentioned, the total cost of true love grain to grain that I have given you ... has not had and will continue to be without any value "I love you.
