Details altered heavily to protect the innocent. 
Once, I came across one of my MA classmates. He was carrying a bag that looked like it was saying "White Power". I was really bothered by this and found it difficult to interact with him in class...although he didn't seem like the kind of guy that would make such an ignorant statement.
I finally got up the courage to ask him what his bag said. He showed it to me, it said "Donny White's Power Washing Service". I saw that, and he said Donny was his brother-in-law and he's really good with rooftop work. He asked me if I needed my house power washed, I turned 3 shades of purple while I admitted that I misunderstood what the bag said.
So...has anyone found that training partner's off-the-mat expressions has (rightly or wrongly) interfered with their ability to train with that person?
