I've noticed that when a colleague gives me bad news on a project I tend to say "Boo...." and of course, if there's a breakthrough then it's "Hurrah!".
I wonder where it's going to take me. When someone starts shouting in a conference call I propose to boo them off the line, similar to good old fashioned pantomime.
Perhaps when I'm next asked where the stats page has got to I'll pluck up the courage for an "It's behind you!!".
