Some do. They just think of it as another chat program I use. I talk about my SL friends all the time.

Yep, they know. My dad would still be on my case about getting a job if he didn't know lol

Yes. My family teases me about it, but they know it's my creative outlet

Nope. I tested the waters once with one friend and let's just say, I ended up saying I was joking around and never mentioned it again.

Yea my best friend knows and used to be in world with me. A couple of my family members know but they think its weird so I just don't talk about it. LOL
