A blunder I committed

How bad one feels if somebody has taken something from you but is not returning it inspite of promising it to do so. add to that a constant reminder to the taker atleast two times. Certainly, very bad..
Sorry to say taht I am such a bad man. Yaar, I took the copy from Balaji Sir, I wanted to read it, i did read some of teh protion but then I just forgot to return it. He reminded me atleast a couple of times( I thought I will give it after I finish it because he might ask a question and what if I tell me that I haven't read).
Now, this man will never even dare to give a book to any of his student. I have spoiled the image of my batchmates. I want to cry, I never meant it Sir. But, he'll feel very abd, I know. I can imagine this from his position. Even I have sploit the condition of the book.
I am Sorry Sir..please forgive me.
These are really annoying instances. One should keep oneslf in other's shoes, think what you would feel if you ahd been the person and then do the task.
