If you could be a door or a window, what would you be and why?

The Wizard lived in an old RV illegally parked on an empty lot at the end of a forgotten dead end street.  He'd been there for as long as any of the kids could remember, and they'd never see the faded Winnebago move.  The weedy dirt patch had been spruced up with a homemade tire planter, a string of fat Christmas lights, and a wooden wind chime the kids said was really made of bone.

Most of the adults thought The Wizard was a meth-head, cooking in his RV, but they didn't know any of the signs and were just judging based on appearance.  If any of them had gone into the RV, like Jake had, they'd know it was clean and followed what The Wizard taught him was "feng shui".
