your boss probably manipulates you. they all do. reason for that is so that you do good work, and work it hard, and do things for him for free, for little compensation. Manipulation = commanding a slave. Though unlike beating a slave with a bat to make him do things, with manipulation the other dude thinks he's free.
Manipulation is going on all over this world. Every day, every hour, every minute.
I never done it, but I'm pretty sure it's not what God intended. I'm pretty sure it's what evil is.
do it to people that deserve it man. Hot gold digging turkeys, and bosses, and government officials. People that are too stuck up in reality.
