Multiplicity

Additionally, regarding 'how do I know if it's really real': It's a difficult question, but the best advice we've ever really been able to give on that is that someone who's acting will start to get tired over time of maintaining a facade of being someone they're not. To quote a system we used to work with a few years back, "Being oneself does not take effort." It's true that some systems do have changes in dynamics, with new people showing up and others deciding to spend more or less time at the front, but that's not the same as someone just getting tired of acting or pretending.
