Eating and being eaten

You lunch upon the hardened heel of bread,
and apple-juice and yellow crisps and cheese.
No mind to wander with the hungry dead;
when hollownesses are filled with such as these.

And such two mouths are quite unlike each other;
As shy as ever doubled mouths were shy:
One breathes in pink with kisses for your lover,
The other hazes mauve to kiss the sky.
