Years ago there was a female Taru following me for about a week (this was when I just started). I always started my day looking at all the (crazy) expensive items on the Auction house, then walk outside and level a bit and finish the day with some exploring. On the third day I actually noticed her standing behind a rock trying to hide lol (her username was sticking out above the rock). From that point on I noticed her at the AH, Gustaberg and in Konschtat as well; always a few feet away from where I was <_<
Mind you I was (and kinda still am) a very shy person so finally by the end of the week I asked her why she was stalking me. Instead of ignoring my post, she walked up to me, did a /shocked emotion and wrote back to me (and I quote): "As a wild-life expert I was just amazed to see a real Galka. I thought they were extinct". After that she just left and I never saw her again.
It is to this day one of the most awkward experiences I had online...
