today is not a good day although the weather is fine, the wind is cool...
today a boy came to my q zone and wrote some words which hurt me a lot...
he said many words to hurt me...and give me a ridiculous reason...
he said:
    i am helping you...you lived so native ,and the social is not native like you...(i wondered i just want to be simple and happy..is it wrong?... )
    you have nothing,and you are nothing,too...Looks? Figure? Knowledge? Character? Accomplishment?...which one do you have??...(i was really unhappy today..)

but now..a friend save me back...she told me how to deal with these mental disorder...and i laughed for her interesting words...
here...i want to hug you...worms sister...
thank you...
and now i just want to stick to my colors which never hurt others and just be myself,who you may think native...
