For this question, think about what impulsive means.
Impulsive means to act without thinking. Usually when you act without thinking, things can go wrong but rarely it might turn out to be good.
Think about a time you said something mean to someone or when you saw someone get hurt, you immediately ran to help them. These events cause very impulsive actions and are very common.
Lets take the example of when you decided to say something mean to someone else. Why would you or somebody else decide this impulsively? Maybe its because you don't like that person or that person was bullying one of your friends. That causes us to act impulsively because we feel hatred or because we don't like seeing people we love get hurt.
What usually happens when you say something mean to someone? Its either the person you said the mean thing to acts also impulsively and says something mean back. Or the person feels sad.
Saying something mean to someone causes bad effects and naturally we regret it.
