Doors and Windows

The entrance of light can be through either a door or a window. But the window is better at letting in the light because it is always willing to do so. The door on the other hand, has to be opened and is by its very existence a closed entry. If I want light then I can go out by the door or sit by the window.

Light is by nature a straight traveller. It will pass through any that wants to allow such movement. A door is a dense object, thick and not at all transparent. (mostly. Why is a glass door called a door, when clearly it has all the properties a window, yet its disguised as a door)
A door is a security, it is protection and it is a closed entry. What are we keeping out? It isn’t the light, because we have windows. Interestingly the very things we want to keep out are people. These same people have doors too. All together we can claim that the humans have invented doors, to keep out the light.

Since light is what we crave, if we all gave up doors then we wouldn’t need windows. We could lay in the light all the day and went night comes we could sleep in the light of the moon and the stars.

What would we then have to fuss about? Its the doors, open the doors and the light will come in.
