But ALL teenage poetry is derivative. The relative badness of it depends on what you decided to imitate . . . . at least I had the sense to imitate Kipling and the Scottish border ballads -- forms that don't require much actual work . . . . I can still toss off a Kipling parody when required . . . . .
Say it ain't so!
I really think Roethke's "My Papa's Waltz" is one of the most beautiful works of literature of the 20th century. It's a very simple poem, composed in common, simple language with simple rhymes and simple meters, yet it addresses the complicated ambivalence of a son's love for his (possibly brutal) father. Judging by your handle, you're a woman, and might not fully understand the father/son theme, but it's a popular theme among great poets.
For a different take, try e. e. cummings' "My Father Moved Through Dooms of Love." It's another masterpiece (and it was cummings' personal favorite as well).
