Meaning to poem Oh Oh by William hathaway?

Life isn't what we expect, eh? One minute, we're gently waving to a choo-choo, dreaming of being president and first lady, and the next minute we're confronted by fifty Hell's Angels, "poised and growling." ---- A different opinion

A poem doesn't always need to have a meaning - any more than any other kind of language does. (What does it 'mean' when someone says 'Good morning!' to you? It just means 'good morning').

William Hathaway's Oh Oh is a joke poem. It shows you a scene of two young people who are probably in love doing slushy things at a level crossing while the train goes by. Once the train has gone by, they see a menacing group of Hells Angels waiting on the road in front of them.

The poem puts you into a soft, romantic, contemplative mood - then it springs a surprise on you by facing you with an unpleasant reality.

It is just a prank poem: like when your brother crept up behind you while you were watching your favourite episode of Barbie in Swan Lake and yelled 'Boo!' in your ear.
