What's the worst thing you've seen a wife do to her husband?

I was giving away some garden plants at a big yard sale. A fiftyish woman walked up, pulling her husband by the arm. He was maybe 60 years old, crying quietly, tears rolling down his face. She was spitting mad at him, her mouth pinched in anger. She said 'He's gone blind! The therapist said he needs a hobby like gardening.' I suggested some Lambs Ear. She said 'No. Give me the cactus.' It was a really sharp, spiny cactus. I was astonished, she wanted a cactus for a blind man! God help the man who has to depend on a cruel wife.
