Dear Sasha, Thank you for your letter! Sorry for havent written to you for so long but I was busy all this time. Well, I am very glad that you have passed all the exams! Congratulations! (I am very happy for you!) I guess, you should relax your body and mind after exams. And the best way to do it is to go for a walk! You know, my favourite sports are baseball and swimming, but your mum gave you a good piece of advice! Basketball is a good choice for you! As well, all teens in Russia prefer hockey and football. But everybody can choose something else Wow! Your brother has just come from Australia! That must be great! So, how was his trip? Was it successful? Did he enjoy the weather there? Sorry, I must finish now, because I have to revise for my tomorrow exam. Hope to hear from you soon. Best wishes, Sergey
