I called my Father in Law for advice on how to find a wall stud before I put up some shelves. He was very patient and helpful carefully explaining it to me, how to measure, how to drill a tiny test hole in the wall with my smallest drill bit.
I couldn't resist pranking him. After we spoke I used ChatGPT to alter an image of the wall to make it look like this, texted him proudly 'found it'!
According to my Mother in Law, the poor bloke had an apoplexy when he saw the image 😂
