Apparently I said to a black guy 'you're my negro'. I forgot my hardhat back at the shop, and a coworker called me from the receiving dept to let me know that it was there, and that 'Darren' would have it. I said back to the guy that called me 'cool, Darren is my neighbor, he's got my back', to which the guy who called me said to 'Darren' "Hey, Dave says you are his negro". When he got back on the phone, I told him "I said neighbor, dude. He lives next to me." and my coworker, who is black as well, said 'Oh'. When I got back to the shop to grab my hardhat, 'Darren' kind of looked at me funny. And he lives across the alley from me.
