Can They Truly Be Separate?

I’m a big profile perv. I love to see what people share, how they talk, or whether they’ve decided to keep it blank. Either way, I tend the find the 1st Life tab the most interesting, as so many will put something about keeping RL separate from SL. I assume they mean that they prefer to keep the details of their real lives a secret and quite possibly their second lives are a secret from those in their real lives, as well. However, I am always left wondering does anyone truly believe that its possible to keep them entirely separate?
Isn’t the real you the one typing on the keyboard? Isn’t every thought you share in SL coming from the brain (or lack there of) in your real life head? Don’t you dress to appeal to yourself? How is it possible to be so completely separate unless your entire existence here is a complete and total lie? Even then, you are bound to have a few honest thoughts slip through the cracks. Even a catfish tends to share some truths about themselves.
I suppose its not really important. It’s just something I wonder about from time to time and always makes me look at the people that write that as kind of odd. Why do you need to announce to the world that you’re keeping a secret? As a person with major trust issues, it tends to make me leery of them regardless of their intent and pull away.
