Last time I was in officemax, I asked if they had any left-handed kid's scissors. Guy says, no, why would we have those? I say, for left-handed kids? He says, "Oh, you just should have kept slapping his hand until he gave that up and used the right one." And was totally. Not. Joking.
Sad but true .....people that were left handed were forced to not use the their left hand. They were told that they were doing it wrong....
