Buildings are masters of paralyzing deception.
With concrete portals of entry, you seldom know what the next room or the next level holds. Peeling back the layers, perception-changing encounters serve to transform you as an outsider into one of the in-groups (pun).
When you are due to make an exit, the step out the door is accompanied by a flush of sorts - relief, freedom; a clysmic renewal washes over you.

Buildings. They lie to the people outside.
