It's easy to say all this now, but back then I was pretty much asking to get laughed at.
Not that it stopped me. The answer to the question "So, will anyone mind if I knit?" often determined my accepting or declining of invitations anywhere
Nowadays I read about people who take their knitting into pubs and it's not all that unusual
, even sexy. Trends come and go. We have people like The Yarn Harlot blazing trails and bringing the cool back into knitting.
ETA: and now e-readers have made it a LOT easier to knit and read at the same time. no need to "hold a book open".
