I petted an opossum once, it was playing dead therefore safe to touch.

Not sure if this counts, but on my install of nobara whenever I hover over an icon in the home bar it relocates to the bottom left corner of the screen, leaving an empty space. I can still interact with apps by clicking on the empty space where the icon used to be so it doesn’t brick my home bar, it’s just really annoying.

Unlike billionaires, some parasites are beneficial to humanity (there’s a species of wasp that lays its eggs in plant-destroying caterpillars, and leeches can be used as bait while fishing).
