How do I correct officers who were my partners last week?

You wanted this rank. Now it costs you something — the ease you had with people who were your equals a week ago. Do not pretend this is unfair. You knew what the rank meant when you took it. The mistake is thinking the friendship and the duty are the same thing and must be protected together. They are not. Off duty, be their friend. On duty, you correct what is wrong. A man who cannot separate these two will fail at both. What you feel — the wish to be liked, the fear of the cold look after — is not new information. Every sergeant before you felt it. It changes nothing about what the post requires. Choose the correction. Let the feeling pass through you unattended.
