Our reading
An editorial interpretation.
The speaker issues a brisk, rhyming command to stop smiling and drop the linen. The wording combines a bossy demand with a teasing suggestion of undressing. Its sing-song rhythm makes the order sound comic and cheeky, even as it calls for immediate attention.
