Controllers Can Only Lead Or Follow

Point of view of a Controller:
Imagine that when you're walking with someone you know, you have to either be in front of them or behind them.
You can not walk beside them.
Not because the path or aisle is too narrow, but because you are not comfortable unless you are Leading the person.
If you are following them, it's either because you see them as an authority figure whom you admire and want to be associated with, OR you don't see them as above but you are "submitting" to their lead grudgingly, resentfully, and only because you can't do something without them; OR, you don't want them to see what you're really doing behind their back, and you don't take their "lead" seriously (you're the 'real' leader).
You have to be either the leader or the follower, you don't actually comprehend "cooperation", "companionship", or "equality".

If the other person asks you to please stop following them or leading them and walk beside them, you will take their request as a command, and either follow it because you see them as the Leader, or argue with them for saying it because you see yourself as THEIR Leader.

The only exception to this is when a Controller sees another person as equally awesome and elite as themselves, so they see them as a "buddy" or a "partner". But the joke is on them, because Controllers usually choose other Controllers to be "buddies" with, and it's only a matter of time before the power struggles start to show.
