Was it really important?

For some reason this morning, I was meditating on the time I corrected Michael Jackson. I think maybe it was Rolanni's plaintive post about people who mistreat shared printers that reminded me of it.
( What's the default? )

There's a principle somewhere in there -- along the lines of do no harm, look before you leap, and similar adages. Software should only do something when conditions are met? Not sure, but I still think it was important enough to interrupt Michael. After all, I would rather have a car that sits there in odd circumstances than one that runs away. But maybe that's just me.
