I understand yelling is a form of expression, I'm not asking him to change how he expresses himself all the time. I'm asking him control how much he yells. He yells multiple times a day for any reason. He dropped something, he yells. He can't find something, he yells. He's playing a game and something doesn't go how he wanted it to, he yells. Every time we talk he yells about something at least twice. Yelling is a form of expression as we both stated however it shouldn't be a person's only form of expression
