dear kelly,
thank you for your recent letter. i was very glad to get. in your letter you asked me some questions.
in your letter you asked me about sport. i believe that it is very important to have a healthy lifestyle a going in for sports. as for you, you should train every day. also, it is very important to believe in yourself and in your abilities. i think, if you are well built, you shouldn't lose weight. but if you have excess weight, you should do it.
that's all for now.
write back soon.
best wishes,
