Dear Tommy,
I am really feeling bad that you are being troubled by overweight these days. I have read an article
about overweight kids. It is said that overweight kids don't exercise enough or eat right. Some kids are
overweight because fast food restaurants serve the wrong foods or it's a problem of genes. No matter
what causes your problem, I suggest you go on a diet or just eat less for half a year and see the result.
Also, don't forget to take more exercise. You know, every afternoon after class I play basketball together with my classmates.
Hope you feel better and look forward to good news about you.
Yours,
Li Hua
