Eyesdropping is essentially eavesdropping with your eyes. When someone looks at
something that is not theirs. The thing that the person is looking at does not necessarily have to be confidential but it
just has to not be theirs like a computer
screen or a cell phone.
"Raymond, stop eyesdropping, look at your own computer
screen."
"Liz,
don't you have
better things to do than to eyesdrop?"
