Now it's out of the bag

D wanted to make tea, so I gave him the basket of tea bags and told him to choose the kind he wanted. He picked up a box of Celestial Seasons tea and took out a bag. "What is this?" he asked.
"It's a tea bag," I answered. I realized that he probably didn't recognize it as a tea bag, because he's used to seeing me make tea with Lipton tea bags, that have a string and a tag, but the Celestial Seasons tea bags don't have them.
"It's a little bag that holds the tea," I continued. "The tea leaves are inside."
I turned my back to get the hot water, and when I turned around again, D had torn open the bag and was pouring the tea leaves into the cup.
Hey, it makes perfect sense--that's how we use everything else that comes in a bag!
