Let's take this idea to its logical extension. Not only do your directs see you first as their boss, but also everyone else sees you as your directs' boss, not as your directs' friend. When your behaviors aren't easily understood as normal manager behaviors, others in the firm will wonder why you're not effective or not reasonable. They will assume that, regardless of any previous relationship, your decisions will be based on managerial factors, not friendship. If they ever find out otherwise, you will not be taken seriously for much longer.
