Red Wasps have to be the most aggressive, pissed off creatures in the entire animal world.
And to actually get stung by one or more is even worse. Feels like a fucking hot poker for a good length of time. Have gotten stung by some the last 2 summers and you don't even see it coming - they just see you and get you.
Many years ago, I was cutting grass on a hot day. Sat on the back steps to take a swig of cold beer. A red wasp was hovering right about eye level and within arms reach. I swatted at it with my hat, and missed. The next few seconds were like in slow motion. I saw everything develop before my eyes, yet was powerless to stop it. He had avoided my swat, then repositioned where he'd been hovering. I actually could discern his intent from those black bug eyes, and I swear I heard him say, "Oh yeah fuck stick, well how do you like this shit?" Then I saw the back half lower...and it's like he suddenly put it in reverse, and he hit me just above the knee! Yeah, they hurt, but I've had one sting worse, and don't even know what it was. Helping a buddy put up a tree stand near Waverly. I felt a critter crawling on my forearm, on the outside portion where I couldn't see it. As I started to instinctively swat at it, whatever it was stung me. I continued the swat, and got it off, but the sting was done, and it felt like someone drove a nail in to the bone of my forearm. It ached for 3 days.
Snake story: Fishing on Lake Eufala, snakes in trees everywhere. Saw them all day. Bud gets his lure stuck in a tree overhanging the bank. He carefully inspects as he glides us in with the trolling motor. No snake in that tree, but as he's getting his lure, the wind swings the back of the boat towards the bushes and my fucking asshole bud doesn't give a shit, and I start looking in the bushes, and I say "snake", but OH HELL NO, he's got to get that lure by God, and right now. I got up, yelled "snaaaaaaaaaaaaaaaaaaaaaaaaaaaaaake" picked up a paddle, and got to the other side of the small bass boat, as far away as possible, and the big fucker fell from it's branch, half in the boat, half out. Thank God, the half out was the head, and it slithered in to the water as I stood there with paddle in the air cussing and screaming.
