Well I've been knitting in public quite a bit. Including at work, though I'm told it's distracting to hear "click, click, click" while somebody's on the phone. But since nobody has told me to stop, I'm gonna keep right on doing it. I do have quite a few people stop and watch for a few minutes, then make asinine comments. I usually just smile and nod.
Wisdom is knowing what to do. Skill is how to do it. Virtue is getting it done.
That which does not kill you, isn't trying hard enough.
