Made fun of a post-doc lab instructor that was under the lab director's purview.
I shit you not. He got upset that someone was - verbally - making fun of this guy. He was a goofy as fuck guy, so I see why 18-22 year olds would do that. I wouldn't because he was a good guy with a good heart, he just looked goofy, acted goofy, and plain old WAS goofy, but that's not enough for me to make fun of someone.
It is enough, actually, but I would never do it maliciously, and I would always do it to someone's face, and it would always... always be good-natured, not intentionally cruel.
