oh I get it now.....my parents had really better watch out in relation to any electrical equipment in their flat...and particularly in relation to 'earth wires'....the inference being? well it is all coded into that ALDI advert....

let me think...I can remember that ALDI ad being coded out...so many years ago now...perhaps everybody should be alerted to the above...in relation to a bit of electrical equipment but what?

black and blue wires....don't touch the plugs 'just in case'....
