RealID - oh there you are!

I've given one person my RealID and I already feel I've given out too much.

I trust my friend. RealID is perfect for us - I play on different realms and different factions. He refuses to even try horde and says he doesn't have time to roll on a different server. We'll be able to keep in touch easier this way.

However I still feel as if my ability to do something on my own without someone knowing about it is gone. It's not about needing to keep something secret. I'm not sure how to describe it. It's like some days I like to go to the park. Does that mean I'd like my friend to have me on gps following my every movement? There's nothing to hide but there's nothing that needs to be shared either.

Anyone else understand what I mean?
