Dear Sally,

Thank you for your letter. I’m fine and I hope that you and your parents are fine too. In your letter you ask me who helps me with my homework. I’ve got a brother, but he never helps me with my homework. My friend Joan has got a brother too and he always helps her with her homework, but then she helps him with cleaning his room. We do a lot of homework because my Maths teacher and my English teacher are very strict. My parents think it is okay to have a lot of homework. They always say, ‘ Our teachers were strict too, and so we learned a lot.’ Well, so what can I do? Joan’s parents say that she needs some free time so that she can play or meet her friends. Thank you for your photo. I think you look so sweet. Bye. I hope to hear from you soon.

Love, Sarah
