That's not tragedy, that's misfortune.
And it's random chance. I was riding in a car, carpooling with a guy from work, and the sunroof was open (his car). A bird, with considerably better aim than yours, shat on his shoulder. While he was wearing a suit, and we were riding on the Long Island Expressway.
He was not cursed. He was just shat on. It happens. Birds ****. Sometimes people are under them.
Tragedy is finding out a parent has cancer, or someone has been in a serious auto accident. It is losing your home, or losing a partner or sibling or friend to addiction. It's the love of your life leaving for the last time.
It isn't shitting birds.
Causation does not imply causality. Get a grip.
