Sometime our reaction to dissatisfying events or others negative actions or perceived attacks can be strong and heavily laden with emotion. In these cases acting precipitously can lead to undesirable results.
Initial reactions are valid and can be useful in the moment but whenever possible a pause to reflect before taking action is a prudent risk management approach.
What Risk?
If your position is iron clad and your reaction appropriate the risk of adverse impacts is lowered; However, the reality is our subjective assessment usually comes first and objective analysis requires a little more time and consideration.
Just in case your emotions are driving a subjective perspective of the event or other persons behavior, taking a moment (even hours or days depending on the complexity) to make sure your response will lead to the outcome you seek is well worth the effort.
This is really just basic risk management. That is, there is a very real risk whatever you do (from nothing to a furious proclamation) will exacerbate and escalate the problem.
Suck it up
Some times you have unquestionably been wronged. In these cases forcefully and clearly stating your position and expectations can be a valid approach.
Unfortunately, the other party or stakeholders might not hold the same perspective and your forthrightness could prolong the path to an acceptable solution (acceptable to you) or even deter it entirely.
It may not be as emotionally satisfying but in some cases it just makes sense to suck up your self righteousness plan an approach that is more likely to achieve what you seek, even if it offends your sensibilities a bit.
After all what is more important a brief moment of emotional satisfaction of attaining your objective.
