Take One Home For The Kiddies

On shallow straw, in shadeless glass,
Huddled by empty bowls, they sleep:
No dark, no dam, no earth, no grass -
Mam, get us one of them to keep.
Living toys are something novel,
But it soon wears off somehow.
Fetch the shoebox, fetch the shovel -
Mam, we're playing funerals now.
