As we Surfers know, sometimes we have trouble with our computers.
I had a problem yesterday, so I called my neighbor, the 11 year old next door, whose bedroom looks like Mission Control and asked him to come over.

He clicked a couple of buttons and solved the problem.

He replied, ‘It was an ID ten T error.’

I didn’t want to appear stupid, but nonetheless inquired,
‘An, ID ten T error? What’s that? In case I need to fix it again.’

He grinned … 'Haven’t you ever heard of an ID ten T error before?
‘No,’ I replied.
‘Write it down,’ he said, ‘and I think you’ll figure it out.’
So I wrote down:

ID10T
