No, its not being misunderstood.
On this forum there are some pet hates - these include:
- Downlights
People who remove lights or switches without noting where the wires go
Neon screwdrivers
etc
The mere mention of any of these will produce an avalanche of snide comments and derision. Don't take it personally, its not just you - do a search on any of the above subjects and you'll soon spot a trend.
No actually the most intelligent way to test something, in this case whether a cable is live, is to use the correct equipment and follow the safe isolation procedure.
In your statement you failed to show evidence of either.
Are you sure that was a neon? More likely the non-contact type which does not use a neon lamp. If it was a neon then you have some serious electric fields in that loft. Are you building an anti-gravity space craft up there?

Sparkticus you are correct, it's one of these http://www.ebay.co.uk/itm/MAGIC-TESTER-Multi-Test-Screwdriver-Cable-Fuses-/120745836147
The instruction book advises the user that putting it near a socket is a reliable indicator of whether said socket is live or not.
Taylortwocities - yes I noticed the trend. Seems some people are so eager to jump on any mention of one they shoot at someone who's actually even agreeing with their view on it.
Riveralt. But my dear fellow I wasn't testing whether the cable was live or not, as I had planned to remove it under isolated conditions regardless. I was testing the screwdriver. I apologize if this was not completely and blatently obvious.

My pet hates include:
fuse board (when referring to an MCB CU)
trip switch...
Anyone else care to add theirs?
strip light "starter motor" and the expression "It'll just be a fuse"
Thank you all, this has been an excellent response, though I am slightly worried about Bernard Greens' thoughts; and I am a little concerned that nobody mentioned that you should avoid touching an earthed conductor whilst using one!
But putting these things aside we are all in agreement that firstly, given the right conditions neon screwdrivers do actually work.
Secondly, under the correct supervision by you as time served men, they could be used to teach an apprentice to have respect for the 'power' that he/she is going to be dealing with during his/her career.

The regs say 2.5mm so you cannot use 4mm.
As you haven't got an RCD the electrics are dangerous.
( they apparently weren't dangerous when the same "electrician" installed the system for the previous owner of the house and before RCDs became known about ).
