Analysis of Then, When You Were Sweet Sixteen

I recall a day, a sky-blue day,
Still in my head, yet far away.
When first you led my mind astray
And left me vanquished, come what may,
The day I saw you cool, serene;
When you were simply sweet sixteen.

For, as swinging years were new
And careless days, about us, grew
And you walked, sudden, into view
Along the leafy avenue.
The day I saw you cool, serene;
When you were simply sweet sixteen.

Your hair shone brightly in the light,
As noonday sun had reached its height;
As you came dancing into sight
And I would gaze, as well I might,
The day I saw you cool, serene;
When you were simply sweet sixteen.

I knew that from that moment, there,
A certain stirring charged the air
And by that lime tree yonder, where,
You passed me by without a care.
The day I saw you cool, serene;
When you were simply sweet sixteen.

And thoughts came flooding, unforeseen,
And such a day had never been.
Yet still, the thrill is evergreen
When you were, then, the Maytime Queen.
The day I saw you cool, serene;
When you were simply sweet sixteen.
