On my tour through the SL11B regions I found out how aliens build their crop circles. Later I talked to an SL11B greeter. She was a really nice and helpful person. During our talking the 50 feet woman appeared. She thought the platform could crash because of her weight but I could convince her that my weight was much dangerous because I had eaten some stones for lunch. Then the girl shrank to a micro particle and we had to pay attention not to trample her down. The greeter had to talk to a guy who started a strange discussion about truth and lies in Second Life and that the avatars aren´t honest.
My personal impression: To be a greeter is a hard job.
