skin

Obedient daily dress,
You cannot always keep
That unfakable young surface.
You must learn your lines-
Anger, amusement, sleep;
Those few forbidding signs
Of the continuous coarse
Sand-laden wind, time;
You must thicken, work loos
Into an old bag
Carrying a soiled name.
Parch then; be roughened; sag;
And pardon me, that
I Could find, when you were new,
No brash festivity
To wear you at, such as
Clothes are entitled to
Till the fasion changes.

Philip Larkin.
