Dear...,It was great to get your letter. I'm really sorry that I couldn't answer earlier.My grandma is much better now, so I hope that soon I'll come back home. If the doctor lets her stay alone, I'll come back on Monday. It was so pleasant to hear that you all are missing me. I'm missing you, too.It's nice that you are taking karate classes, but as for me I don't find this sport very attractive. I'm really sorry but I don't think I will do karate with you. You know, I prefer less active kind of sport. Playing chess for example. I think we can discuss it when I come back.My grandmother sends her love to you.Hope to see you soon.подпись(своё имя)
