Here's the scenario. At some time in the next few days, whenever is convenient, a perfect clone of you pops into existence. It is you in every way: same age, same memories, same exact thought pattern, except he/she is a few feet away from you. From this moment on, you are separate individuals, slowly diverging into your own personalities as new experiences occur.
Share some ideas. What might happen on the first encounter? Would you get along with your clone, or would you argue over the computer/bed/car/mate? What harebrained schemes would you enact that required working in perfect harmony with yourself?
I would call my clone "Ni" (two) and myself "Ichi" (one,) to make the distinction clear, and leave Ni home to run errands and finish organizing the house like I planned to, while I go to work. We would probably spend a lot of time in co-op activities like workouts, sparring matches, video games, and future planning. Most likely, after a few months, I would send Ni up to Maine to work with my ex-girlfriend and win her back, while I would continue working and fund his living.
The biggest problem would be money. I landed a sweet job in January but the job market does suck, so I would be supporting two people until we figured something out. The lucky thing is that my life goal is to raise healthy, successful children, and see to it that my ex-girlfriend is married happily, so I (Ichi) could live with watching Ni succeed in my place. If anything, that would free me up for dating other people.
