I think just being yourself is going to be more than enough. It should be, I don't think changing yourself for someone else ever really works. Having people refuse to say what they need and where though, that's frustrating. It becomes a guessing game half the time. We really are complicated. Which can lead to wonderful things, but also sometimes it means we end up a pain in the ass to those around us.
A lot of pizza and red paint accidents? I kept a duel identity for a very short time while in the military service. It didn't last all that long, and while a measure of privacy leaves with it when that's blown, it was for the best in my case. Not for everyone, though. I respect those who choose to or have a need to do their work undercover.
