My brother does, but I won't tell him much about it. I don't want him to ruin my fun.
My mom has dementia which is a type of Alzheimer's disease. She never would have understood it if I told her.
I have a cousin who told me, brought me in and got me started in sl.
She left to get in shape and is now happily married.
I had a rl girlfriend who was a WoW player. She didn't really like sl.
She told me the good stuff was too expensive. Meh.
A good family friend knows about sl. He's ok with it.
That's all from my family who knows about sl.
