The text of my last lesson Once my daughter asked me: - Mom, why didn't you buy me chocolate? - I'm sorry, I forgot. She remembered that sometimes I make a shopping list. And now she proposed: - Ok, I'll make a list for you, and you will not forget next time. She went to the table and confidently scribbled something quickly. I was surprised because my daughter couldn't even read. When I looked at the piece of paper, I saw a rectangle drawn there. - You see, I drew a chocolate, - she said. - You will not forget now. And I didn't forget, because I had my daughter's list. All genius is simple!
