This line is dripping with satire. The speaker is mocking the party-goers for experiencing “mental strain” from such activities as counting cucumber seeds. Furthermore, the suggestion that a non-alcoholic fruit punch may revive them is meant to inspire deliberate eye-rolling and scorn on the part of the reader. Without explicitly stating her intentions, the poem encourages the reader to share in her mockery and contempt for the partygoers and their activities.
