I Was Having Trouble With My Computer

So I called Joseph, the 14 year old next door whose bedroom looks like Mission Control, and asked him to come over.

Joseph clicked a couple of buttons and solved the problem.

As he was walking away, I called after him, “So, what was wrong?”

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.”

Joseph 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 that little boy.
