What are you afraid of?
Whatever fears a person carries inside are the root of every horrible act he or she inflicts on other people, including but not limited to: lying, criticizing without supporting, stealing credit, going beserk in a traffic jam, excluding someone, sabotaging someone eles’s opportunity, suggesting a makeover, hitting, complaining about an otherwise lovely evening, divulging secrets, yelling, cutting in line, assuming, and so on.
Yes, sometimes people who do these things are just oblivious of other people. Then again, people who are that self-centered are that way for a reason (see above).
If you are afraid, do not to try to make others more afraid than you. It is tiring.
