Joy / Sorrow

Grief mingles with light,
It imposes, pushing its
Way unbidden, just as 
Joy comes without an 
Invitation into sadness.
They are two of a kind,
Unlikely twins of a sort
On the path of feelings,
Emotions on a spectrum
Swinging pendulum-like,
With much less precision
As sorrow is tinged with
Happy memory, missing
Any nuance on the way,
As if it were not nuance 
Enough experiencing the
Extremes all at once, and
Jumbled altogether, a mix
Up, contradictory and odd.
