"Do you know where I could find dill?"
I said, "Yes, Kroger has dill. It's in the spice aisle."
He said, "No, not that kind of dill. I need the kind you use to make pickles."
By then my eye was really bothering me, and my arm was getting sore from all the grocery bags hanging off it. My patience was ebbing away as I explained that I'd never made pickles and didn't know what he needed. He started describing it as "a green plant that grows to about three feet tall with feathery little leaves," and I said, "Oh, you mean fresh dill?" He said yes, and I said, "Kroger has fresh dill. It's in the produce section." He smiled huge, thanked me, and parked farther down the row from me. I loaded my groceries, got in my car, and tried to pry the wafer out of my eye. When I backed out of my parking spot, the old guy was standing there saluting me like a soldier.
