Often confusing

Faces.

Look in the mirror, what do you see,
The face of those you will never know.
A face that never belonged to you.
A face now rubble, neath some forgotten bog,
A face that never saw the miracles you saw.
Look close, for once it lived,
As you do, but never could,
See itself blemishless.
Gaze upon yourself,
And realize this face is not yours.
It is only an heirloom,
A trinket passed to you,
As you will pass it on. 
A privilege, of the highest order.
Look close, and live,
For you have much to live for.
To show you are worthy of it,
And to inspire the next to be proud.
And when this face passes on,
Will they have a mirror to gaze upon,
And see you, as you see them now.
Strangers in time, will they know,
Of this face that you lent them.
This face that you gaze upon.
