We only share them to make us feel better in difficult or awkward situations. People who use them mistakenly think that they explain what is going on in the moment. They are used more as a defense rather than offered as a thoughtful analysis of what has taken place.
Excuses never help us get better or learn from a situation. Only being honest with ourselves will accomplish this. Taking responsibility for what has taken place. Especially in the most difficult situations for they never solve anything.
Furthermore, they never answer the question “What do we do now?”.
