"Culture is always..." [ditty]

Culture is always   something that grows
      yeast or love or yoghurt
when it is living   watch how it flows
      just ask Humphrey Bogart!



==========
An answering verse, responding to this:
Culture is always something that was,
Something pedants can measure,
Skull of bard, thigh of chief,
Depth of dried-up river.

--Patrick Kavanagh, "Memory of Brother Michael"
