There was once I recalled when I had to manage impulsivity. I had reacted to a situation in such a rough way due to impulsivity. My sister had called me in a very rude way, using the word which hurt others. I had reacted very roughly by asking her to keep quiet in a very rude way back. This ended up into a physical fight, but as an older sister, I did not stop her.
If I could turn back time, I would rather keep quiet and not hit it back to her but tell her nicely to stop or maybe to tell my parents about her bad behaviour.
