Why do people do it?

Hoarding office supplies is a crime.

In some offices.

In other offices, hoarding office supplies ensures that when you realize you need multi-colored hanging box file folders with a 2'' capacity - that you'll have them. THEN you can FINALLY organize your project drawer with a color coding system that will allow you to file and later access documents quickly and easily.

Plus, I plan to share office supplies that I've put on the order list. Really, I do.
