Behold, I stand at the door and knock!

I have not had a real walk today so far.  However I took this this image of the main door of the old school while I was going out to visit friends, I have featured this building before several times in different ways.  So how could I give it a different twist?  I decided to have a tight crop on just the door.  A door can have symbolism in many different ways, so I wonder what it means to you?
