Besides having no gear he is getting horrible advice from an adult ump. He is saying not to toss as a kid, try to be calm and keep them in the game. He was saying that if you toss them you will have to deal with them later. I'm a firm believer that it doesn't matter how old the ump is, if the coach steps over the line then he leaves. Yes, you will have to deal with them later and if he thinks he can walk over you then he will. If he knows you won't put up when his BS then he won't be as likely to start.
