A teenage boy with a Mohawk sat across from me, sneering. I’d seen that look before. Why was it a problem to knit in public? “My grandma knits.” I ignored him. “So what are you making, Grandma?” Mohawk’s voice was ugly. I arched my eyebrow. “A cashmere cock ring. Your grandma ever knit one of those?” The kid’s eyes grew wide, and he suddenly became very interested in a four-year-old issue of Teen Vogue.
