I like how I came in to work today - when NO ONE else is here because of the holiday week - all set to do an experiment, only to find that the kit I am (was) using has everything but the ONE thing I need to make the experiment work.

GRRRRRRR SCIENCE RAGE.

I mean who does that? Who uses most of something and doesn't order more? That's like putting an empty carton of milk back in the fridge.
