ID error

USA

I was having trouble with my computer so I called Richard, the 11-year-old next door whose bedroom looks like Mission Control, and asked him to come over.

Richard clicked a couple of buttons and solved the problem. As he was walking away, I called after him:
— So, what was wrong?
— It was an ID ten T error — he replied.
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.
Richard 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: I D 1 0 T.

I used to like the little shit.
