My wife has a couple of external hard drives that she keeps her pictures and other transportable files on.  Recently, she’s been doing some cleanup work on those drives, making sure all of the files exist on one of the drives so that the other can be set up as a synced copy.  She completed her work, and I told her that I could do the sync for her.  I was planning to use rsync and, probably, set up an Automator script so she can resync them anytime she wants.  I was quite amused the next time I came to her computer.  There, on her keyboard, was this:

I should back up and fill you in on the fact that my wife is quite the fan of all things Alice in Wonderland. Her iMac is named Tweedle, with her internal hard drive being named Dee, and her primary external hard drive being named Dum. Her portable drive, aptly enough, is named Dinah.

So, here I was staring at this note that she had written to me.  As I said, I was quite amused, because the whole thing struck me like surgery, namely the practice of writing in permanent marker which limb should be operated on - or removed in the case of amputation.  The similarities were uncanny.  And, in truth, I was quite appreciative that she left that note there - making sure that I did not, after all, amputate the wrong drive!
