Steve J Waterfield's "True Love" reads like a long grumble about a spouse, and that is the joke. The speaker lists her habits one by one: she talks at length but won't listen, leaves every light on, snores, rings the doorbell despite having a key, and criticises the room he has just painted. Each pair of rhyming lines adds another small irritation, and the bouncy, chatty rhythm makes it sound like a man letting off steam over a cup of tea.
The turn comes in the last two stanzas. Despite everything, he still loves her, calling her his "trusty sidekick" and "very best friend." The final couplet, about not wringing her neck in nearly forty years, is the punchline. The poem suggests that lasting love is less about grand gestures than about putting up with each other's quirks. The mood is warm, cheeky and affectionate, and the complaining turns out to be a sign of how close the two are.
