Two sisters fall out over nothing more than a taste for coffee versus tea, a small, funny squabble told in four tidy lines.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Molly, my sister and I fell out,
And what do you think it was all about?
She loved coffee and I loved tea,
And that was the reason we couldn't agree.
About this rhyme
Text confirms two sisters (the narrator and 'Molly, my sister') fall out over coffee versus tea.
Two sisters fall out over the smallest possible thing, one liking coffee and the other tea, and that is the whole story. It's a rhyme about taste rather than temper, over almost as soon as it starts.
Ask afterwards which one the child would have picked.
