Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.

-Bible (NewTestament)
Colossians 2:8.

We drink one another's healths, and spoil our own.

-Jerome,Jerome K(lapka)
  Idle Thoughts of an Idle Fellow,'On Eating and Drinking'.

Wesit†and lookout attheboysintheir happy play†we kneel still with one little cheek wistfully pressed against the pane†and we go and stand before the glass.We see the complexion we were not to spoil, and the white frock† Then the curse begins to act upon us. It finishes its work when we are grown women, who no more look out wistfullyat a more healthy life; we are contented.We fit our sphere as a Chinese woman's foot fits her shoe, exactly, as though God made bothöand yet he knows nothing of either.
