For me, the remaining yarn after frogging sits in a tangle on the sofa, viewing me with a definitely accusatory stare.
It seems to say...
"Here I was, all nice and arranged in a really beautiful way and YOU just yanked me right out of my comfortable little haven. And all because YOU weren't paying attention".
"Do you know how hard it is to get twisted into all those shapes you put me into to get this pattern? It's like "yarn yoga"!!!!! And then you couldn't leave well enough alone but had to UNDO all those positions. NOW you tell me you're going to twist me all around yet AGAIN!!! "
"Where's the phone? There has to be a hot line for abused yarn and I'm calling and REPORTING YOU RIGHT NOW!"
The above is as good a reason as any to re-knit that yarn right away! If you just re-roll it onto the ball it will still lie there and mutter. The only way I've found to shut it up is to just re-knit correctly as quickly as possible.
I wonder if I've been in "Knitville" too long......:?? Oh, well, let's just hope we don't have to frog the same area more than once. That's when it really gets ugly!!!
