East is East and West is West
East is East and West is West (and never the twain shall meet).
Prov. Two things are so different that they can never come together or agree. (From Rud-yard Kipling's poem, "The Ballad of East and West.") I had hoped that Andrew and I could be friends in spite of our political differences. But, in our case, I'm afraid that East is East and West is West.
