Sometimes

Sometimes it's easy to think about you.
Our memories overwhelm me,
I feel the touch of your hand in mine,
and my eyes sparkle with joyous delight.

Sometimes I can't think about you at all.
My brain shuts off the pathway to the pain, 
My lungs stop taking in air,
and my heart, momentarily, stops beating.

Sometimes it's easy to talk about you.
Words fall from my mouth,
stories flow like vintage wine, 
and my smile is as wide as the horizon.

Sometimes I can't talk about you at all.
Sentences fail to form in my head,
my voice dries up like a parched riverbed, 
and my mouth is clamped like a vice.
