(Read Diorama first)
I had lazily left the roach in the sink. Typed the above post. Went back to the kitchen to get an orange from the fridge. And found the roach moving again.
I knew they can creep around headless for days, and survive nuclear radiation. But all things that breathe air drown, and I swamped the foul thing!
Yet it is still alive, antennae cast. There must be hope for me after all.
Yet it is still trapped, though in a much bigger hollow.
