I think a haiku is a form of a Japanese poem with a specific structure, but Google’d it to be sure.
hai·ku/ˈhīˌko͞o/
noun
- a Japanese poem of seventeen syllables, in three lines of five, seven, and five, traditionally evoking images of the natural world.
I wait on the train
To walk in the cold outside
To work and get paid
This evokes the image of the natural world for many workers living in the burbs.
