The milk of human kindness eh.
I chuckled when I saw that line, reminded me of a Billy Bragg song called The Milkman of human kindness, from his first album I think. It had the line "I love you, I am the milkman of human kindness and I will leave you an extra pint". I wept tears of mirth when I heard it, how corny, but still a good song.
I bought the album for 'Between the wars' and 'A new England', good old Billy, a complete raving socialist but likeable nonetheless, always made sure his albums were sold for less than market price, didn't like his politics, but respected his loyalty to those principals.
