Back on Thursday one of my coworkers asked to borrow my ID because one of the chuckleheads in her building had locked her out and her ID was in her purse at her desk. Security is NOT a big issue on our campus so I said sure and gave her my ID so she could get hers and bring mine back. I was going through a growing out phase at the time that ID photo was taken and she looked at it and said, "Wow, your forehead is really-REALLY high." She looked at the photo, looked at me, looked at the photo, looked at me, smiled, "Yeah, keep shavin' it, you look much better this way."
Not that she's going to make up my mind one way or the other, but that may have been one of the best, most spontaneous moments of positive reinforcement EVER.
