Doors are interesting things.
Doors say a lot about a culture, a structure, a person.
Doors are used for a variety of purposes. Some protect by keeping out while others protect by keeping in. Some are merely a visual barrier while others permit visibility. Some are always locked, some can be locked, and some never lock. Some swing, some slide, and some flap.
Doors are made of many different materials depending on the purpose and the means available to its designer: Metal, wood, glass, plastic, fiberglass, paper, fabric, rock.
Doors can also instigate emotional responses. Some doors look pleasant, or creepy, or stir memories of childhood. Some bring to mind fairy tales, fantasy worlds, or nightmares. A locked door can be reassuring or it can be deathly frightening. An open door can make you feel welcome or insecure.
Doors also hold a lot of symbolism for us. A closed door can be the end of one possibility, while an open door can be the beginning of a new opportunity. Some symbolize a transition from one way of life to another. A door can symbolize a person's character, or the state of his heart.
Doors are an every day aspect of our lives. We take for granted a great deal about doors both on a conceptual scale and on an individual bases.
What more can be said? Knock knock.
