On Aggression, Stingers

 Honeybees have valuable honey stored in expensive wax. They're kind of laissez faire, live and let live. "Oh you need this flower? Cool bro, I'll be done in a second here." They're not doormats but they don't make a big deal out of small things.

 There's yellowjackets, who look like right assholes and are. They have worthless and hideous paper nests. "Oh? Looking at me funny and/or not looking at me funny? I'll kill your entire bloodline." They'll sting you just because.

 Then there's bumblebees, who are so docile it's hard to understand how they survive in the wild. Many folk doubt bumblebees have stingers at all.

 Yellowjackets really are assholes for no reason.
 It's karma, they're the remains of an asshole immortal; almost certainly was such an asshole he killed himself.
