Using an old laptop as a second monitor?

Hey again guys, I recently purchased a new laptop and was wondering if it is possible to use my old one as a second monitor to the new one? Both laptops are running windows 7!
Sorry if this is insanely stupid question! Any help would be appreciated, thankyou!

No , laptops don’t have any inputs to their monitor, only outputs to feed a stand alone monitor or TV..
