Scissors

In college, my friend told me if someone hands you a pair of scissors it means they want to fight. I can only imagine the amount of accidental wars started via scissors. Our mothers always tell us not to run with scissors but why don't they tell us not to hand someone scissors?

What if the great tragedies of our times could have been avoided if someone had just set the pair of scissors on the floor and walked away? Could we have world peace by now?

All I know is I'll never hand anyone a pair of scissors. You never bring a pair of scissors to a gunfight!
