Analysis of Apologetic Postscript Of A Year Later

IF you see this song, my dear,
And last year's toast,
I'm confoundedly in fear
You'll be serious and severe
About the boast.

Blame not that I sought such aid
To cure regret.
I was then so lowly laid
I used all the Gasconnade
That I could get.

Being snubbed is somewhat smart,
Believe, my sweet;
And I needed all my art
To restore my broken heart
To its conceit.

Come and smile, dear, and forget
I boasted so,
I apologise - regret -
It was all a jest; - and - yet -
I do not know.
