My favorite day is Friday, because it is on Friday that I leave school. On this day, you can forget about the lessons for a while, postponing them to Saturday or Sunday. And then immediately there is time for fun walks with friends in the yard and your favorite hobby.I like to play online computer games, but on weekdays my parents forbid me to do it due to the large amount of homework. But on Friday everything is possible! On this day, I am not only allowed to play on the computer, but also go to bed after ten o'clock in the evening. Therefore, on Fridays, we often watch fascinating family films on TV with our parents until nightfall.
