what's the use of doors (if i don't feel like music)?

the question came from windows (oh, technology), who got jealous, being somewhat less musical. or it came from the window (where you where standing), and you got jealous, being somewhat more territorial. but music can be technical and territories don't have windows. and windows are smaller doors, they're doors for the eyes. therefore, doors are windows for the blind. or afraid. relax.
