Doors and Floors

So I walked into the library today.  Bleh.  I dislike libraries, esp the local ones.  Well, the inner door was propped open, like it usually is, so I walked through it.  Until it realized it was an automatic handicapped door, and decided to close on me as I walked in.  Hit me square in the side of the head and down my side.  My head is STILL throbbing.

Stupid doors.
