"One day when I was sad I asked an old monk what his remedy for sadness was.""Sing a favorite song", he said. Then he added "Oil always comes to the top of the vinegar."
Clearly he had encountered one of the problems of salad dressing which persist to this day, when we try to mix them. (I guess *Newman had the answer.) Anyway, ordinary daily life is often a bit vinegary, spiritual things are often soothing like oil. But look at the trouble oil has been causing lately. Ordinary life is full of oil and vinegar but it makes a good dressing.
As the dying lettuce leaf said from the depth of its bowl "I like to be well dressed".
NB * "Newmans Own" is a brand of salad dressing created by Paul Newman.
