YM: Is that your hair?
YT: No, I don't think that anyone spins with human hair.
YT: But I am saving up some of my cat's fur...
YT: Huh? Why? How is it any different from wool?
YT: Ok, what about cotton?
YT: *pause* What are you wearing?
Maybe it never occurred to him that his clothing has to be made from something, and that something has probably been spun. Perhaps not by hand, but still, it's the same as what I was doing.
And how is turning wool or cotton (or cat fur) into yarn and/or thread gross? Would he have preferred that I be using human hair?
Anyways, I just think that the conversation was funny.
