An Uncommon Purpose

We don't remember life is brief
Until we see one go.
And we forget that time's a thief,
So common seeds we sow.
But, then some flowers bloom at night
And some, just once a year.
These wonders rarely catch our sight
Unless they happen near.
They momentarily play a part
To brighten up the gloom.
And though you're gone, you're in my heart;
A rare and fleeting bloom.
