At lunch time she eats much vegeables like cucumbers or tomatoes or carrots and etc!She like to eat these with a pieces of chicken and of cause with porridge like buckwheat or oatmeal etc
at dinner tim she usually eats 2 eggs with portion of salad and at supper she drinks a cup of milk or yogurt!She goes to gym 3 time a week and I think it helps her to keep fit herself 

Well

Sunday is my favorite day because I don't have classes.

I don't have any homework! I usually get up early,

but I stay in bed for about an hour! I take it

my laptop and Check my email. I sometimes

send text messages to my friends in bed or chat with them online.

I'm going to eat

when I get hungry and want Breakfast!

After Breakfast I go to a meeting

to meet my friends. We

we usually ride our bikes to the Park. We drive around and we have a lot of them

fun! Sometimes we play football or other games. Often we

forget lunch!

And also

early evening. We have a big dinner,

and then I watch TV with my family. I go to bed around 10 o'clock

but I read in bed for half an hour before I went to bed.

I'm turning it off

my light and go to bed.
