All my love for you Era, sweet baby Jeezus, some of you went through some serious shit.
My contribution to this thread is peanuts in comparison, about 2 weeks ago, I had a short but heated discussion with one of the engineer guys over here.
It pretty much came down to a right idea, wrong execution type of deal. My manager called me to clarify the issue and, while busy, I took the time to meet this guy, but right out of the gate he already popped off, claiming the job he did was ok etc, some back and forth and a few interruptions later it all comes to a head. Culminating in him brushing my shoulder in a really dismissive way and saying "I didn't understand it."
Holy shit. I nearly grabbed his hand and escalated the situation, but ended just glancing at my manager and walking away >:[
It wasn't exactly mean, as much as it was disrespectful. Really rustled my jimmies, never been so disrespected and I was right.
