The 'show no anger' rule is one that I really must abide by, a skill I must perfect.

Showing your anger does not really get other parties to appreciate your ordeal... believe it.

Simply make a short and fair statement about the matter, and leave it at that.

Yeah, I know that this is better said than done.
But we must work at it.
As I write this, I am just recovering from a 'showed my anger' conversation.
... and I have resolved to keep it out next time.

My anger didn't change anything anyway.

You all have cool, anger free weekend.

Kiss Kiss.
