A tiny domestic tiff: an old couple fall out because she has money and he has none. It is over in four lines, more comic shrug than real argument.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
My little old man and I fell out;
I'll tell you what 'twas all about,—
I had money and he had none,
And that's the way the noise begun.
