By misunderstanding
One of the worst ways to become upset (and sometimes the most embarrassing) is through misunderstanding. Quickly jumping to:
I’ve been cheated!
I’ve been insulted!
I’ve been robbed!
If these feelings are followed by the realization: no you actually were not … then we’ve caused ourselves emotional distress all for nothing.
Clarity first. Then calm consideration.
What happened here? Was I wronged? Have I been injured in some way?
If the answer is yes, then feel what you feel.
But still: clarity first.
