my knife`s set was stolen

my knife`s set was stolen when i was washing dishes in the gastronomy class, i had finished to wash dishes and my friend was cooking in the same pleace, he asked me about the temperature of the fire, i was explaining about it , but i had already forgotten my knife`s set on the table, by the time i had explained the temperature of the fire he had already dissapeared with my knife`s set then i was talking with the director about the problem then his secretary had already heard and she was seek his adress of my friend in the computer, after that she gave me the exactly adress, in the afternoon i went to my friends house but i didn`t found him , i was asking to his neirbour about him and people said that he is a burglar, it seem to me that i had a bad experrience in my life and i though that it was a joke.
