Actaea

The fact that Ventorum ran away only confirms that I was right not to support him.

Four friends are out for a walk. Some bullies start harassing one of them because he has long hair. Two of the friends immediately start acting aloof, as if they have nothing to do with it, and the third goes even further, saying, "Really, why are you walking around with that hair, are you a girl? Go shave it off quickly!"
After this incident, the offended friend decides not to hang out with his old friends anymore and finds new ones. This decision shocks his old friends, and in the end, they add, "So, we were right not to support you, since you betrayed us."

I can even write in my textbooks that it was our valiant scout, John Doe, who organized the coup.

And he also shot the First Consul.
