Allow me to drop some knowledge on you, Freudian style.
I am the id, the devil on your shoulder who operates solely on achieving pleasure. I have no inhibitions and no restraints. I want to eat, I eat.
My opposite is the superego, the uppity angel on your shoulder. Nobody likes him/her. Nobody at all. He/she/it sucks. Lots.
The person who we haunt and screw over is the ego, who balances us and allows me my pleasure realistically while also satisfying little goodie two-shoes so he/she/it doesn't nag.*
*Nag nag nag.**
