Hi, ( имя человека, который прислал письмо)
Sorry, I havent written you for ages, because I was busy at shcool.
As for me,  in my spare time like walking with my friends, watching films. Besides I`m keen on listening to music. Me and me friends often go out at the weekends. As a big part of teens in Russia we like visiting cafes and cinemas, sometime we go shopping to relax.
Tell me about your broter`s birthday? Where was the party? What are you presented him?
Hope to hear from you soon.
Yours,(Свое имя)
