Answer:
Can't take back what you've said.
Step-by-step explanation:
One of the problems of speaking with a clouded mind, be it a heated argument, sadness, happiness, etc, is that one is later slave of what one has said. It's impossible to take it back. But, particularily during a heated conflict, we tend to say what we really think. This can damage relationships, but, what damage them the most, is not to speak and communicate our feelings or thoughts.
