Dear Marta, It’s been a month I haven’t heard from you. I hope you are well. I had a terrible day at school yesterday. My friends and I were playing volleyball in the school yard when I suddenly fell and twisted my ankle. I didn’t feel much pain at first, but later on, it started hurting badly. I had difficulty to walk, so my friends helped me around. They took me to a hospital and stayed with me until my mom and dad arrived. The doctor said it was broken and I needed to rest for a month. We came home last night and I feel better now. This incident also made me realize how valuable friendships are. I don't know what I would do without them. So, I want to say I feel very happy to have such a good friend like them and like you too. Yours lovingly, Helen Why does the writer feel happy?

Dear Marta,
It’s been a month I haven’t heard from you. I hope you are well. I had a terrible day at school yesterday. My friends and I were playing volleyball in the school yard when I suddenly fell and twisted my ankle. I didn’t feel much pain at first, but later on, it started hurting badly. I had difficulty to walk, so my friends helped me around. They took me to a hospital and stayed with me until my mom and dad arrived. The doctor said it was broken and I needed to rest for a month. We came home last night and I feel better now. This incident also made me realize how valuable friendships are. I don't know what I would do without them. So, I want to say I feel very happy to have such a good friend like them and like you too.

Yours lovingly,
Helen
