What is the purpose of the event?

I want to remind everyone that this Friday is clean-up day—what that means is we’re going to put a couple of large garbage bins in the cafeteria so you can throw away old papers, out-of-date materials, and all the other junk that’s piling up on or around your desks. It’s actually a fire hazard to have stacks of papers on your desks or piled on overhead shelves or cabinets. So, please, everyone, mark this Friday, from noon to 5, on your calendar as a time to dump some of your clutter. And it’ll be fun—there will be pizza and soda for everyone who contributes to the bins.
