in my life i wake up get ready for school then i eat breakfast similar to maarit but i do not need to feed chickens or do anything else in the morning. once i am at school i study many different subjects and like maarit my favorite subject is math. then i go home like maarit i do my homework. then unlike maarit i do all my chores right after i do my homework. then i eat dinner and watch t.v until i go to bed. then i wake up and repeat the process once again until the weekend. on the weekend i do nothing i don’t go anywhere with my father i just relax
