man's mind bacomes bigger by having been wronged

Today i got worried by misunderstand.
My teacher said that one of her books couldn't find,she Suspected that i had taken it.while,God knew what i had taken from her desk,which is Confirmed by seeing an another very book she gave me.IT is an english book,which is a Brochure about instron 5585 tensile test machine.I never borrow any books before,let alone english book.But i atoned it and said that i really saw the book and losen it with a smile.When atoning the book ,i asked my teacher if i could borrow the book again.but the answer is very Disappointed :she was afraid that i lose it again.when walking out of her office,i nearly wanted to cry,but i contolled myself.i hope the book will be found again.and my teacher could Apologize to me!
