Alternate Personalities.

Lately I've been suspecting myself of having several alternate personalities. Different ones have the most control at different times. Any time I'm in public with no one that I'm familiar with, the silent/tough/mean personality shows. When I'm with a person I'm familiar with, the extreme/psychotic/fire-loving side that you all know shows. There are at least 2 others that don't show that much but sometimes have a pretty big effect on the way I think. I don't know how many of you have noticed, but I have an intellectual side that decides all of the principles, rules, and philosophies for myself that I follow. There's one other I can think of at this time but it didn't show until just recently. I'm not exactly sure what you could call that side, but it's been affecting the way my body does actions sometimes. It rarely gets control, but when it does happen it's at random times.

The question is, which one of these was my first personality? Or is it locked somewhere deep in my subconscious?
