Let's say it's Friday morning and you have to leave town at noon to drive to another town to see friends, go to a party and lead a retreat on Saturday morning. And say you waited til the last minute to make copies of all your handouts. I know, I know, none of you would actually do that but just pretend that you had a couple of really good reasons for waiting til the last minute.
And say that you had exactly enough time to get everything copied and get packed except that then your printer black ink cartridge ran out halfway through the first set of copies. And then say that you got a frantic call about a client emergency that was going to take at least an hour to manage, not to mention all the worry and concern you're now consumed with. And say that, even though you're running an hour late, the printing job is going smoothly, what with the new ink cartridge and all. And then say, the power goes out.
I'm home now and all went well.
