What's a Door For?

What is a door, anyhow? An opening in the wall? No, that’s a doorway. The door is the thing that closes up the doorway. Or opens it up so that things can go through the wall.

That brings us to windows. What are they for? So you can look out, right? And look in. and so the light can shine in today. And shine out tonight.

Which gets us back to walls. They’re supposed to make it so you can’t see or hear people on the other side, and they can’t see or hear you.

Which gets us back to doors: you can’t see and hear each other through them very well, either. Which means a door is really kind of a wall, but with the added advantage that it’s easy to open when you want to go through or let someone else in. and the best part of all, it can be just another part of the wall if you lock it.
