Argh.

Why did you close that file while I was working on it and hadn't saved?
Why?
Why?
Why?
Why couldn't you have done that before I spent a half hour typing that new bit in?
And what the heck went wrong that made you need to close the document?
It's not like it was the Internet.
Oh well.
It's retyped now.
And I have to admit, I like it better.
But don't think that that gives you permission to do it again.
