What Was in That Cup?

What was in that cup?
It made her laugh so heartily,
That strands of hair were dislodged,
And fell about her cheeks
Now flushing red,
Half with the self consciousness of
Having lowered her guard,
And half with the strain of laughing so hard.

What was in her head?
It rattled around so pleasurably,
That her eyes beamed symphony.
It caught me in my heart,
And set it on fire,
Three quarters full of love was kindling,
With a quarter to move into
And fill my heart, entire.
