I teach Stalking 101 according to my friends
But yes, I often just sit in a quiet corner of a map and F3 around looking at people's bios, characters, etc. Or sometimes I'll sit at Stone Bridge or Bonfire and silently watch the chat. Other times I like F3ing around and seeing where my friends/people on my friend list who I don't know at all are at.
But yeah, I usually get bored in-game so 'stalking' is mostly what I do xD
