I always find this funny. Like on those national geographic shows when animals or insects do something like walk in a pattern or make a noise to have another of their kind wander over for whatever reason. When I go into, say, the Quicksand I sometime speak to myself in that old british voice, "Ahh, there we see the mating dance of the RPer~" Heheh, I'm just being silly. But I do like solo RP. Of course I do it for the sake of maybe having someone wander over. It not only makes the world feel more real to others, but I think it's like a polite and passive way of saying you are free to interact with~! I'm usually more than happy to wander over when I see this, only because my character is super curious and doesn't know the meaning of stranger danger
