My wife and I were shopping and I had accidently stepped on her VERY sore toe.
Her reaction was to scream and call me a BAD name; shoving me outta the way.
A fella going the opposite way in the aisle was almost next to us; reached an arm between me and the wife, asking her if I was bothering her in any way; while keeping both eyes on me.
She had to explain what had just occurred so this Galahad fella didn't knock me out!
Funny now; not quite so then.
I'm guessing the Galahad guy was amused, once he understood what really had happened.
