Bloated egos and lack of humor is expected. Air gets in the brains, we float on temporary highs. Suck a little helium for some cheap laughs, it always works. But the thinning layer of skin will burst, eventually. It always does.
Maybe it'll burst in a booming, cracking pop. Or, a pin prick and deflate slowly and obviously. Like death in a way. Neither way is good, but the float is ending, slow or fast. Egos must die, and will.
Humbling will come. In a heap, by some sort of biological means. The brain runs this ship, like Eastwood said. Don't let the old man in, man. Keep your wit.
