    I was playing at my cousin house. Since his family was rich than mine, he had more toys than I did. There was one on particular I'd always wanted. I put into my pocket when he wasn't looking. I guessed, even at that age, I would never be able to enjoy to playing with the toy or faced my cousin again; I would always know I'd done something wrong. Late on, my aunt drove me home. When she dropped me off, I pulled out the toy slow and gave it back. She knows what had happened, but she thanked me and ever mentioned it again.

    I have received and read your letter, in which you mention that you wanted to lose weight by diet.

    It is only naturally that young girls at your age hope to look beautiful. However, in my opinion, healthy is more important than beauty. For a student, studying is the first thing to consider while appearance is second. So do not let others' opinions to affect your normal life. Therefore, if you do want to lose weight, it is a good idea to do it by getting more exercise and changing unhealthy eating habits. The most important thing is how you keep a healthy state of mind, as it will help with our studies, and will also help you overcome difficulties in dieting.

    I hope my advices will be helpful to you and I'm looking forward to your next letter.
