When I was in college, I worked for a moving company over summer break.

We would often get temp workers for big jobs like office moves and one day we had a black temp worker. I could tell within a few minutes that he was extremely unstable and I went out of my way to avoid him the rest of the day. I just knew he was going to lose his shit and do something stupid. And this guy was fucking massive so I knew I'd have no chance in a physical altercation.

Shortly after lunch, I heard from others that the black guy pummeled another worker and sent him to the hospital.

Never. Ever. Relax.

They just don't care. They'll throw their entire life away over a perceived insult from a complete stranger.
