This is a little late in posting for you to say “if” about anything. You either did, or did not view this video. Geven your number of minority opinion postings, would you have cheered the man on to continue the baseball lesson for the day?
I cheer any parent who cares enough for his kid to spend time with him and discipline him if needed. No, I would never ever advocate disciplining a kid for dropping a ball, but we don't know if that was the cause. Do you believe that there is never a case where corporal punishment is in the best interest of a child?
