   Ah, that's why they use those criminally damaging testers for electrical   
   safety tests.  The ones that can actually destroy computer equipment.

   Not sure how I can perform this test then.  I don't want 240V anywhere near   
   her foot for testing.

   I doubt it was even possible to harm you, even a 9V battery on your tongue   
   just stings.  Mind you if you're up a ladder anything that gives you a fright   
   can make you fall off.  I was painting my neighbour's eaves once and his   
   stupid wife tried to have a    
   bloody conversation with me from below.  It was the only time I've used rather   
   strong swearwords at her.  Her husband found it amusing.

   One day that will fall down and short something and cause a fire, I'd be   
   careful if I were you.
