My father also has only one operational eye, he has never had issues in his life other than the occasional sign brohug while walking on the pave.. He tells the story of once dislocating a shoulder on a sign because it was on the side of his bad eye. Though we all know he's exaggerating.
He loves exaggerating.
“The worst thing I can be is the same as everybody else. I hate that.”
They're cats though.
