Mixed handedness is often the result of people being ‘switched’ when they were children. I was naturally left-handed, but my mom kept putting my spoons and forks into my right hand, and back then, the school I went to frowned on kids writing left-handed. In hindsight, no wonder I was terrible at handwriting. Didn’t know I was left handed until I took archery in 7th grade.
Look up ‘mixed handedness.’ Those are people who use different hands depending on the task they are doing. Only a very small percentage of people are truly ambidextrous.
So does blowing up the bathroom in your dad’s apartment. My husband did that.
He was cleaning car parts with a can of ether in the bathtub. Walked into the kitchen and lit a cigarette. Almost instant conflagration.
