What just happened to me:
I'm standing in line at a UPS store (having just made a deal for a pair of my headphones in the Head-Fi Classifieds) and there's a guy in front of me who is putting mountains of tape on three boxes. He says two things to the attendant that intrigue me:
1) When asked for the address he uses the words "care of Google."
2) When asked how much insurance he wants he says "$600."
I asked him about the boxes, and he tells me that they're speakers that he's sending to one of his friends. I told him that I was in that store because I was shipping a pair of headphones I had sold. He asks me what kind they are. I flashed him the box (Ultrasone PRO 2900) and he got all excited. He said that Ultrasones' are nice, and that he has a pair of "Modified T50RP's. Wood cups. Also known as Thunderpants."
I told him that I was aware of that, and that I had just bought myself a pair of Hifiman HE-500's. He said that those are nice, and that if I'm "into headphones" I should go to a website... "Head dash Fi dot org." To which I respond "I am always on that website."
He told me that I was the first person IRL that he's met who knows of Head-Fi. I echo'd the statement. Then we parted ways.
Fate?
