and afterschool activities, about her hobby and dreams.

She goes to the 7 th form. Her favourite subjects are English and Maths,

improves her skills. She has some problem, her computer is broken and

she does at the library all her homeworks. There are 12 computers and

a big collection of books about gadgets. All pupils come to the library

because of the Internet. Also they like to do sports, take part in

different competitions. But they hate their green uniform.

Stella attends to the Film club and is a beauty bloger. Her dream is

playing the guitar and she studies along on YouTube, because there

isn’t any Music club nearby.

One interesting story happened with Stella. She makes some video

about householding chores . She gave some advices about tiding up

the room and cooking, ironing and do the washing up. After all she had

some questions from readers. One reader asked her about

householding duties and girl answered that she works a lot. She cooks

the supper every evening, go to the shopping, serves the table and

washes up the dishes. It wasn’t truth. And reader that answered her
