I'm sure we've all done a similar thing. I did that over 20 years ago.
First I knew about it was when the drill bit sparked on the live
cable.

It taught me good, better than any teacher could have done. And to
this day I immediately look for cable runs before getting the drill
out. Heck, I even go to the trouble of using a cable detector

Hmm, I might invest in one of these, but i've heard variable reports
on their usefulness/effectiveness.

I was notching the wall in the kitchen with my trusty angle grinder
and discovered a wire running *diagonally* on the wall left by a
previous bodger.

Luckily I peered into the slot and saw grey insulation, rather than
red/black/copper ;-)

Cheers,
