The rubber bands you see here are the worst ever. They serve no practical function, except to aggravate and annoy humankind. Too thin to hold anything substantial for longer than a minute or so they perform no proper rubber-powered task. You may be able to wrap your book or a few pages of paper in them, but within a brief span of time the bands will break, fueling rage.
They are here to test us, to demand that we remain calm in the face of wasted resource, unfulfilled need and outright uselessness. They are similar to some relatives you know, I'm sure.
