Without this there is no action anybody can take...

We can't live in a world where accusations without evidence hold weight, nothing will get done and everybody can just accuse anybody of anything to get their way.

And in retro, if you think a door bell called you a name you probably are unfit to deliver packages to any doors, and should seek mental help.
