If someone with anger issues is struggling to control their temper, great tips are:
1. Find something in your life that you've been through that may relate to what this person is angry about, and calmly share your story. For example, Tom is abnormally angry about not getting his new tool kit delivered on time. So you say, "I understand, one time I waited weeks for my phone case to come in and it upset me very much."
2. Take the angered individual to an isolated and private area. This gives them less triggers and is safer for others.
3. Teach the person coping skills when they are NOT currently having an episode. For example, Chloe is in a good mood while she is painting her nails.
