Could be with a teacher, other students, the school, the training itself. I’ve had a few. Here’s one: I met with a Tae Kwon Do teacher who laughed at (LAUGHED AT) my Kenpo background continually and said it wasn’t real karate, and wouldn’t exist outside of the U.S. He worked us to the bone! That wasn’t so bad you get used to it eventually. But then another student proceeded to tell me how other newbies have thrown up in class before. And a yellow belt actually did throw up that day. It was too much for me. I went once.
And the place didn’t have air conditioning!
