Etymology: Of obscure origin; perhaps imitative: with senses 2 and 3 cf. dander (v.).

"First, in the old days, when I was sick to death
with the horror of my life,
when I lusted to be driven into exile,
you refused that favor—for all my prayers.
But then, when I'd had my fill of rage at last
and living on in the old ancestral house seemed sweet...
then you were all for cutting, casting me away—
these ties of blood you maunder on about
meant nothing to you then."
