beginning to end (tammy's metaphor challenge)

She was the cool breeze blowing
he rolled over the rocks
young stream bubbling
they meet in the mists
bodies interlocked over the rocks
exploding in midday sun

Now his gnarled arthritis hands
stem from spindle tree arms
her seafoam eyes are mindless
she's a scattered breeze blowing
alzheimer's child flows in and out of reality
his stream creaks with age, barely
eeking through the rocks
struggling to carry Charon
on their journey to the underworld
