Shopper

Susan held the can of peas in her hands and thought for a moment… how did she know that there were peas in there?
She grabbed a can of corn from the shelf and looked at it. Was she certain it contained corn?
She took a razor blade and peeled off the labels from the cans, switched them, and smoothed them over the dribble of glue on the can’s seal.
What was in each can now? Was there corn in the corn can and peas in the pea can?
She put them back on the shelf to maintain the mystery.
