I am whatever YOU think I am until YOU get to KNOW me. This is true for everyone else too, of course.. so don't make assumptions about anyone or pass judgment; ask questions. You might just make a new friend.
Assume you are locked in a room with a perfect clone of yourself. NO one will see what you do and the clone will COMPLETELY disappear in one hour. Would you go for it and find out what it is like to sex with yourself or would you do nothing?
