Poem by a Stranger

WHEN I stare in the window
At happiness I see
A lot of children playing,
And one on her knee

Pressed close against her
Like flower against flower:
The earth for their feet,
Heaven for their dower.

Earth-shine, fire-shine
And something blue between
That sends out a fragrance —
What can it mean?

Once I am sure they saw me
And gave a lovely leap,
But I went quickly
Before I could weep.
