You spend nine hours a day, five days a week here. You eat, drink, socialise, earn your living within these confines. Yet you've never seen much beyond your cubicle.
Three storeys below you, a design feature that might save your life one day sits in isolation.
Don't worry though, you'll likely never use it for a real emergency. From time to time you might be expected to play along during a fire drill, donning your fire warden's red hard hat and enjoying your fleeting moment of power as you share jokes with colleagues about not being able to make that 2 pm deadline anymore.
Will you cast a glimpse to either side of you as you stroll along the gangway in an orderly fashion? Or will you fail to notice the hidden space that beckons you to come play? I'll be there, in the darkness. Watching. Waiting.
