Cheek is generally the truth. Weak people offend themselves with the truth. The truth is what hurts. It oozes from the psyche. The truth is fear.
Weak people are scared of themselves.
Opinions cloud the view. If we avoid them, we will understand everything. It is only our opinion about something that makes it good or bad. People are insecure because they have no control over themselves or their environment, or both. If someone is selfish it is only because the people around them allow it.
