An amusing scene I witnessed earlier today: Two adults walk past on the sidewalk, single file. Possibly a mother and father. Or maybe two single parents. Two children walk behind, side by side. A girl and a boy.
Mother: “Elliott, Sarah, let’s walk single file so people can get by.“
Elliott: “We were.”
Mother: “That’s not really— ”
Elliott: “Well I was.”
Mother: [Pauses to reflect on conversation.] “Do you know what single file means?”
