scintilla - a tiny brilliant flash or spark; a small thing; a barely- visible trace.

a beating of a heart,
euphoria,
a scintilla.

a firework of neurones
almost a burst of panic
a scintilla.

a brush of the lip,
flutterings in the abdomen,
a scintilla.

a sharp intake of breath
inflation of lungs
a scintilla.

a soft goodbye
a shadow of gloom
a scintilla.

a crack in the heart,
a browned vignette,
a scintilla.

a disappearance,
happiness then, despondency now
a scintilla

a faded spark,
the lost scent of vanilla,
a scintilla.
