Failing at Yogurt

I timidly opened the cooler lid,
it felt warm, it must have worked.
I cautiously removed the lid from the
ceramic pot and peered inside
only to find liquid milk that sloshed
from side to side, not the slightest
sign of yogurt curd.
I almost cried after all my hard work,
the heating to 160F, the cooling to 110F,
the lamp in the cooler, the towel to hold
it all cozy, the warmed dutch oven,
the love, the care, the kisses, the hope.
all for naught.
failing at yogurt, what is supposed to be
so simple, foolproof, that saves money,
that is healthy and quintessentially local,
what does this portend for my future.
