I don't follow? I can copy a file and then consider the two files to be separate copies of the same data?

What should I have said instead? "We"? "Him and it"? Self-modeling is part of my experience. I'm sure it'll be part of the spreadsheet's experience as well, if it functions identically to me.

I don't see the gotcha at all?
