NAME_1 is a 15 year old first year high school student. He goes to NAME_2' house, to bring him a present for his birthday. NAME_3 is going to be 15 today. NAME_4 goes up to NAME_3's room, which is a typical teenage boy's room, with posters and drawings on the walls. A sound system sits on a stand beside the bed. NAME_4 knocks on the door and yells, "Happy birthday NAME_3!" NAME_3 answers the door and NAME_4 offers him the gift. NAME_3 begins to rip off the paper. I watch as he opens the box. Inside the box is a slave collar. NAME_3 looks at NAME_4 and asks, "What's this?" NAME_4 explains, "It's a slave collar." NAME_3 looks confused and asks, "What does it do?" NAME_4 explains, "It makes you do whatever they tell you to do." NAME_3 looks at the collar and says, "I don't want a slave collar." NAME_4 then explains, "It's not for you, it's for me to give to you on your birthday." NAME_3 then says, "Why would you give me a slave collar?" NAME_4 then tells him, "I'm giving you a choice, if you put it on you will be my slave, if not you can choose to put it on me, in that case I will be your slave, of course we can decide how long for a week or a month." NAME_3 looks at the collar and then at NAME_4, and says, "Okay, I'll put it on." 
NAME_4 says: "wait before putting it on, I have to tell you the rules of the collar.
1) whoever wears a collar will be forced to obey every order given. All people free from collars are masters.
2) The slave cannot remove his own collar or remove the collar from other slaves, only the master can do it.
3) The slave can be ordered to be the sole property of a master or a limited group of masters. In this case the slave will not be forced to obey strangers.
4) The slave can be ordered not only to do actions but also ordered not to do certain things. Such as lying, stealing, or doing harmful actions.
5) You can not order things that endanger the health or life of the slave or third parties. In this case the slave will not obey. "
NAME_4 continues saying : "Once you put it on, it can not be taken off without the master's permission. Do you understand? "
