Once upon a time there lived a nightingale and a blindworm, each with one eye. For a long time they lived together peacefully and harmoniously in a house. However, one day the nightingale was invited to a wedding, and she said to the blindworm, “I’ve been invited to a wedding and don’t particularly want to go with one eye. Would you be so kind as to lend me yours? I’ll bring it back to you tomorrow.”
