I am so angry! The current personal trainer said that I talked and laughed with my former coach, and he was still chatting and laughing with the members! ! Did he?

There is no need to dispute with such a villain. As long as you are yourself, it doesn't matter. The personal trainer said that you talked and laughed with your previous trainer, which is a typical performance of jealousy. It is a very irresponsible performance at work. We don't need to haggle with such a person, as long as we stay away from him, do our job well and let him go. Such little people can be seen everywhere in life. Seriously with such people, there will be no result in the end, but you will be angry with yourself.
