How necessary is knuckle-cracking?
)
September 29th, 2009
The question below this one reminded me of this. I have a classmate who cracks his knuckles very often and extremely loudly. It really bothers me.
One day, I asked him to stop and he snapped at me that his knuckles hurt if he stopped cracking them.
Knuckle-crackers: is this true? Do you experience physical pain if you don’t crack your knuckles? Is it a reasonable request to ask someone not to crack his knuckles during class, or am I being too demanding?
