I'm chairing this committee and there's this work we have to do. It has to get done, or bad things will happen to other people.
We set a due date of today for 11 of the things to be done (by 11 people). How many are done? 3.
(These aren't things that can be done in just a couple of minutes at the last moment, but take a fair bit of time.)
Sometimes, my colleagues are worse than my students about lateness. (But, fortunately, I know that, so we set the date a bit earlier than absolutely necessary, and I sent out a reminder today. Yeah. The thing is, if the task isn't done by the real deadline, there's no way to do it late and push the deadline back.)
