The scorpion and the frog story
Once upon a time a scorpion wanted to cross a brook. On the bank he saw a frog and asked if the frog would give him a ride to the other side.
“Oh no,” says the frog, “If I carry you on my back you will sting me.”
“But why would I sting you when we would both surely perish,” replied the scorpion.
The frog eventually conceded that the scorpion had a point, and agreed to the request.
Half way across, the scorpion stang the frog, and they both began to drown.
“But why did you break your word and sting me, knowing it would be certain death for us both?” cried the frog.
“Because it is in my nature.” said the scorpion.
Its all about personal responsibility.
