Becoming angry is a common intense emotional state found in all living beings. Expressing it is not a big deal at all. We must understand to whom it is expressed.
It is almost impossible for me to digest anyone's anger without a reason. I can understand the situation when I have done a mistake. I don't have any issue to hear any rough thing due to my mistakes. Digesting rough behavior without my fault is the worst scenario for me. I simply avoid those whenever anyone tries to show his anger with me without any logic.
Now it is a scenario like a little object in a solar system achieving escape velocity due to the gravity of a gigantic object.
