"What are you sorry for?"
I can hear my mother saying those words to me today though she said them many years ago.
The chances are excellent that I had just done something stupid (I was a kid, after all) and had gotten in trouble and was pleading with Mom by saying, "I'm sorry" over and over and over.
In all likelihood, this pleading occurred right before a spanking (this was back in the 1960s and 1970s when this was not frowned upon like it is today).
How many times have you said "I'm sorry"...
