Nixon Hurt His Chin Again

I was upstairs the other day when I heard some quick footsteps up the hard wood stairs in Grandma and Grandpa K's house, and then a huge slam!  It honestly sounded like someone had thrown a hard book at the stairs.  There was no sound for a second, and then Nixon started screaming.  I ran down to see what had happened, and he had missed a stair, and slammed his chin right into the corner of the step.  Right where he had had stitches before!  I was so scared that he was going to need them again, but it didn't cut the skin, thank goodness!  It was pretty sad though!
