Today I want to talk about howling my favorite sport. My favorite is definitely football. I do not play football on a professional level, but going out into the yard to kick the ball is a sacred thing. I know the fans were screaming, I try to go to all the matches that interest me, if I missed even one I am very upset. As you understand, I love football!
Сегодня я хочу рассказать о своем любимым виде спорте. Моим фаворитом безусловно является футбол. Я не занимаюсь футболом на профессиональном уровне, но выйти во двор по пинать мяч это дело святое. Я знаю кричали болельщиков, я стараюсь ходить на все интересующие меня матчи, если я пропустил хоть один я сильно расстраиваюсь. Как вы поняли я обажаю футбол!
