dear aleks,
thanks for your kind letter, i was so strongly glad it to receive. you ask to answer me your questions-is good.
usually i spend in front of the tv about two hours per day, and sometimes even till five o'clock. i watch tv so much, how many it is required to me, depending on need. more often i look informative programs, or what are interesting to me at present. i don't love the program not bearing in myself of sense.what programs you look? why you them look? when you them look?
it is the end of my letter.
answer it as soon as possible.
all the best,ann.

anne was reading a book when suddenly she heard a weird noise. she opened the window but she did not see anything unusual.then a green monster appeared in the garden.at first she screamed in horror but then she realized that it seemed familiar. she turned on the garden light and she was surprised. the wind moved her green dress on the washing line up and down making her think it was a monster.
