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.
