Umm…I know anger is always labelled as a negative emotion but anger is actually important — there are different ways of expressing it. Hiding it is not really a solution. Of course, when you are in a bad head-space, you do have the tendency to act without thinking and that can lead to unpleasantness, but I always believe in “better out than in”.
When I am angry, I usually go quiet. I don’t know if it applies now, but once upon a time, not far from the recent times, the first thing you’d notice about me was my smile. I always had a smile pasted on my face. Always. The easiest way to figure out I was angry was if the face was devoid of a smile.
