Once when I was a little kid, my older brother was mad at some wasps, and started squirting oil down a rain spout were he knew they had a nest. They came flying out of that spout and all went right after him. I was standing right beside him, but not one touched me. He got stung a bunch of times, and (I hope) learned a valuable lesson about leaving wasps in their nests, alone. I learned that if you don’t mess with wasps, they don’t mess with you.
