Like the Yin and the Yang

Like the yin
and the yang;
the left
and the right;
the thunder
and the lightning;
in each other
they delight

She
loves the mountains
He, the sea;
an adventure
the two seek

She is
the imaginary
He, a reality;
on the hem (of both)
they find harmony

She
believes in luck
He, in endeavour;
a struggle (for both)
to keep it together

She
believes in miracles
He, trusts the usual;
He and she and she and he
a usual-marvel...
