You bought the same dvd player from Sam Goody's. Half price because it was broken.
Now you take the dvd player home and it was working. Would you take it back to the store and ask to be charged full price?

Just a question...

My question is, you knew your neighbour, hence you were given the player in the first place. Generosity begets honesty.

But to a person you don't know... would you be as honest?
