When a pig writhes around in manure and some manure is flung onto your suitcoat, one does not say “Say there, Mr. Pig! Pray, would you please refigure your manure-writhing technique so as to minimize the frequency and severity of airborne manure-particles? I dare say my suit coat is rather less dandy than it was before, and I think you’ll agree we’ll both be better off by keeping the manure where it belongs!”

You move further away from the pig, because it’s a pig and it’s rolling around in a big pile of shit.
