I avoid such displays.
Every once in a long while something hits me unexpectedly though. I was in a bagel place and as I was sitting down I glanced and espied a little girl in a wheelchair. Appeared she'd be born with some sort of nerve disorder...and I had to sit down quickly; put my face down to the tray and tried to control this hot rage and tearful sorrow...took a deep breath and wondered wtf was wrong with me...
