"don't even get me STARTED about purling. I thougt I had it DOWN, then my mom came out to visit for Christmas, and basically told me I was on crack."
On a similar note, I once was showing a left-handed knitter how to knit in the round (I am right handed) and she was like "what are you doing?"
Me: The regular knit stitch
Her: oh.. I don't do it that way
Me: do you do it like this? *I purl a stitch*
Her: How do you know that??
Me: Well, I've read a lot of knitting books... *bluster, bluster, brag*
Her: That's really impressive!
She gushed so much that I didn't have the heart to tell her it was just the reverse of a normal stitch. She's a really new knitter so probably in a month or so she'll learn how to purl left handed (ie: knit right handed) and remember me as a blowhard. Oh well.
