Stop saying knitting is something only old ladies do.
I learned to knit when I was a kid. I knit scarves for my friends when I was in high school.
I knit when I became a stay-at-home-mom.
I’ve knit off and on my whole life. I didn’t consider myself “old” then and I certainly don’t consider myself “old” now.
Kids knit. Teenagers knit. Women of all ages knit. Men of all ages knit.
Knitting is not something only old ladies do.
So just stop it.
