The time - yesterday, 11am. The place - my mother-in-law's new apartment (I'm still not done with all the drilling). The mission - installing a toilet paper holder in the master bathroom. The drill penetrates the ceramic tile with some difficulty, then sinks a couple of millimiters, then gets stuck. I apply more pressure, yet more pressure, something gives, and the drill breaks in two. No water this time. After a while we discover that every time we flush the toilet, the power goes out, the downstairs neighbour starts banging on the wall (what's with him?) and the burglar alarm uses its backup battery to call the police and play a "power supply is being tampered with" recording!
