One pair of Yaya's shoes are getting a little small for her feet, but she loves that pair and still wears it to school. Unfortunately, it has to be tied and tied again. Today, on the stairs, i saw the shoelace is getting loose again and asked if she wanted me to help. And she stop to let me tie it for her. I was telling her about the fact that it is too small for her feet because her feet grow, and she asked" why my feet grow?""...." "why don't the shoes grow as my feet?" "what do you think?" "Is it because that they don't have mouth like i do, therefore they can not eat, so they don't grow?"....
