I am one of the weird exceptions. I am guessing that I am actually lefthanded because my handwriting is very inconsistent with my right hand. There is this “test” people do where you rub your stomach, and pat your head. Then you switch to the other way round. When I was younger, it was a challenge to do either one. But nowadays, I find I can wrestle with one dog and scratch the belly of the other dog and be aware of what each hand is doing. I guess every dog is born on a different day. – Chuck
Why if I’m left-handed, I can only snap my fingers on my right hand well?
Practice. I have learned to snap (not crack) thee fingers per hand. It just takes practice and patience. Though stiff fingers don’t snap well.
