Calm your tight pusillanimous individual. There is such thing as soap.
I understand, you can clean it, but it's still disgusting. I don't have a tight pusillanimous individual, by the way. It's unsanitary. It's unlucky if someone gets stuff on by a bird, but if a prank forces the bird to poop everywhere, that's grotesque and unnatural.
Whats done is done, get over it and have a laugh.
So your argument is that if something is over, get over it? Really? That dismisses like, countless arguments ever made.
