When I go to the grocery store, I bring my own reusable bags along with me. I have some light nylon bags that fold up quite small, so I can keep them in my glove compartment.
At the checkout, I pulled out a couple of bags. “I have more if we need them,” I told the checker.
My son chuckled. “Yeah, she has a bag of bags.” He finds it amusing that my nylon bags are themselves stored in a nylon bag.
“Well of course,” I replied, “what would you keep bags in?”
“A box, of course,” he teased, “don’t you know anything?”
“I have two teenage children,” I laughed. “Of COURSE I don’t know anything!”
