The world needs asses.
And crooks. And liars. Everyone has a role. Even if that role is only to make you look good.
But don’t let baddies work you into a froth. Walk a mile in their shoes and you’d probably be the same person.
It’s better to simply take note of who’s an ass, and stay clear in future.
Life is too short to be upset by things outside of your control.
Him being an ass is his problem, not yours.
