my working day
I have to get up very early on Monday, Tuesday, Wednesday, Thursday, and Friday. I dont go to school on Saturday and Sunday. After waking I have a quick shower, brush my teeth, get dressed, and prepare my schoolbag for the day. I dont need to make sandwiches, as I get lunch at school.
I start out quite early in the morning, at half past eight, after having breakfast, if I have time. Then I walk-or run if i am late-to the bus stop, which is a couple of streets away from our house. The bus takes us to the school, while we are busy talking, singing, reading or throwing things at each other. Then we go into school, go to our classroom, to register with our class teacher and receive any general information concerning the school before going off to the first lesson.
The first break is at about half past ten, when we can go outside to meet our friends for twenty minutes, and talk or play some kind of game. Then come the next two lessons, and then another break for dinner. At dinnertime the school hall is laid out with tables and chairs, and we queue up at a serving hatch, where we cfn order any of a number of different foods. Next we pay for the food at a separate counter, and then go off to sit down and eat. After dinner we have two more lessons before we go home.
When I get home I usully go up to my room and listen to music or read, or take the dog out, and after an hour or so have supper. After that I eiher do my homework if I have any, or go to visit one of my friends and we play or listen to music together.
