Life Imitates Student Management

I once told a colleague flustered with trying to give announcements to groups of students: "Don't ever make announcements unless they're important, and don't speak often.  If you talk all the time about things that aren't really essential, then nobody will listen when you are.  They have to know that when you get up to talk, it matters."  I am, therefore, not in the least surprised to read this.
