["I was walking out of the store the other day and walked right into the glass pane! It was so clean, I didn't realize the door wasn't open! Talk about humiliating!", 'Oh no!  I remember doing something similar when I was younger.  There was a pool outside of our screen door.  I went to run and jump into the pool from in the house and smashed right through it!', 'Yeah, there was no cool way to play it off either.  I swallowed my pride and left as quickly as possible.']
Gotta roll with it!  Just play it off at that point.
