i like to go to school during the week as i get to know something new every day. but most of all i like weekends. i do not have to get up early in the morning. i can stay in bed longer. during the weekend i can do everything i want. but this doesn’t mean that i do nothing at all.
usually i read books and listen to my favorite singers. i meet with my friend and we walk along my town and fancy funny stories about people around us. sometimes when the weather is good i take a ride on my bicycle to the nearest park. i enjoy being on the fresh air as much as possible. some of my friends go to the countryside every weekend. it is some kind of a family tradition for them.
in whole the weekend is the great time when all my family gathers together. i have an opportunity to spend more time with my father. he likes to play different active games with me . for example, last week we spent half of the day playing football. we get tired a bit but we were happy.
