Analysis of Threnody

Lilacs blossom just as sweet
Now my heart is shattered.
If I bowled it down the street,
Who's to say it mattered?
If there's one that rode away
What would I be missing?
Lips that taste of tears, they say,
Are the best for kissing.

Eyes that watch the morning star
Seem a little brighter;
Arms held out to darkness are
Usually whiter.
Shall I bar the strolling guest,
Bind my brow with willow,
When, they say, the empty breast
Is the softer pillow?

That a heart falls tinkling down,
Never think it ceases.
Every likely lad in town
Gathers up the pieces.
If there's one gone whistling by
Would I let it grieve me?
Let him wonder if I lie;
Let him half believe me.
