George wants Bob to throw the cat off the roof into the pool to see what would happen.
If the cat gets hurt it's my fault, but if I don't I lose George as a friend.
Bob stops to think what would happen if he would follow through.
I'm not throwing the cat
Today would be nice!!
Bob sees that he can either throw the cat or let it go about its life without getting hurt.
Throwing the cat will be fun, but could result in the cat getting hurt. George will remain Bob's friend If he doesn't throw the cat, the cat will live longer, but George said he won't be Bob's friend anymore.
Bob now makes his choice to not throw the cat into the pool because he would rather have the cat unharmed than have George as a friend.
Bob thinks his decision over to see if he made the right choice. He believes he did because the cat didn't get hurt and he realized that George wasn't a good friend.
