Borrowing and Theft, Part II

Hi,

We have said that one may not borrow an object without informing the owner. The same is true regarding 'borrowing' something as a practical joke, whether intended to irritate or just to have fun; this constitutes theft in Jewish law.

(Shulchan Aruch Choshen Mishpat 348:1)

Have a good day,
Mordechai
