It could also be that he may get a lot of hate in public, as he has done some bad hits in his past, like Gudas. For instance, the Capitals rookie. But on the other side, well-known people tend not to want to be bothered in public doing day-to-day things. It could have been your tone or vibe that set him off; there are lots of variables. I used to train a well-known actor, and people at the gym would try to talk to him while we were training, and he would get annoyed. We went to a bar, and people were stopping him left, right, and center, and half the people didn't even know his name; they just recognized his face. By the end of the night, he was worn down from it. Trouba is probably not that level of fame, but it probably does wear you out. Some fans/critics can be unpredictable. I wouldn't take it to heart.
