Why do flies rub their hands together?
It’s like when you eat a packet of chips or a messy food, you have to rub your hands to get the crumbs off. Imagine if you’d been trapsing round in poo all day, you’d feel like washing your hands regularly too, unfortunately i havent seen a fly dip their feet in water and soaping down so I guess there’s a limit to how much they can clean off.
