There is the one group of muggles that sees knitting and things "ho hum."
Then there is the other group that sees a k2p2 ribbed scarf and thinks you're discovering plutonium. It is a member of this group that saw me knitting on Palindrome last week and actually thought my row counter incremented by itself.
This is not the first time I've heard this. How would that work, anyway? Would it increment when you flipped that needle around to knit the other way? When you tapped it on a surface, kind of like one of those handheld stroke counters for golf?
When I then show the questioner how I rotate one side of the counter with my fingers, they are much less impressed. But still thinking that k2p2 is rocket science. And cables? Oh, man. That must be for very advanced knitters.
I frown at them. Learn to knit, people!
