Bella's List of Dos and Don'ts:
DON'T put graffiti on your colleague's flyer. Especially when the graffiti is grammar related. Especially when your grammar correction is WRONG. Learn the nuances of the apostrophe, and then, how about contacting me and asking me or complaining to me about it? It was not my flyer, but it was on MY friggin' bulletin board. And YES, I KNOW who you are. ASSHOLE!
DON'T arrogantly tell me you'll just "bump" your colleague if your course does not run. Sorry I could not accommodate you to the f'ing letter, but we don't BUMP here. Ask your union rep, ASSHOLE.
DON'T put your colleague down for asking that an often misunderstood and little known policy is made more clear in the catalogue. YES, our dean has something against this colleague, which is why said dean has used this little known and often overlooked policy against hir. SCREW YOU for being so dispassionate about a problem that could bite YOU in the ass soon, too (knowing how capricious this dean is)...ASSHOLE.
DO congratulate a junior faculty member on a minor accolade. I heard about that (yeah, people gossip here a lot) and I appreciate your collegiality.
DO attend earnest and hardworking newbie's program. My heart broke at the sparse numbers, but I was heartened by the numbers of sweet old timers who did not have to come, but did just to be supportive.
SORRY I ended my mad rants with an all caps insult, and could not formulate an all caps appreciation of the kind colleagues. But I thank the compassionate and caring ones, I thank them from the bottom of my heart.
