He that toucheth pitch shall be defiled therewith.

For cleanness of body was ever esteemed to proceed from a due reverence to God, to society, and to ourselves.

Its only when you Clean your doorstep that you have the right to criticize your friends for not visiting

Then bless thy secret growth, nor catch At noise, but thrive unseen and dumb; Keep clean, be as fruit, earn life, and watch, Till the white-wing'd reapers come.

All will come out in the washing. [Sp., Todo saldra en al colada.]

Certainly this is a duty, not a sin. "Cleanliness is indeed next to godliness."
