...Why is that an insult? Do people like feeling they are in a simulation being controlled by an exterior being? Do people like feeling they are being controlled by anyone/ anything?
Or, is it more saying this person is an irrelavent character? Also dumb. We all play the lead character in our own lives- surely? We can't experience them any other way. I suppose if there's some bigger narrative going on, some of us may be more important than others. God knows what that narrative may be though.
...Whoever that guy is, some people may adore him. Others may find him arrogant and ignore him. He probably means absolutely nothing to some people who could well think you are more interesting/ have more value- to them.
The sad thing is- you're giving this person all this power over you even when they insult you. But, I get it. Sometimes we go for the very worst people (for us) we can go for!
