The only slightly worse thing I can think of is telling whoever it is that you're angry, and having them not understand what you're saying. A tad worse than the person not understanding your point, is going to great lengths to tell them by working the plan of the telling out in your mind thoroughly in order to get your point across accurately. Finally giving the telling one last go round, enunciating carefully, using words you know they will understand, checking your spelling, you carefully tell the person with whom you are angry one. last. time. And they still do not understand. Then you realize all this time it was you that needs to understand.
