There is a further reference to that as well; "When the stars threw down their spears," yet again comparing the tiger to Satan.
In the poem "We Real Cool" Gwendolyn Brooks uses the concept of diction itself to present the problems an individual may encounter when dropping out of school. Initially the poem starts out with an allusion to what most young teenagers would enjoy-"We/lurk late. We/Strike straight." It continues with some of the good points: "We sing sin. We/Thin gin." These concepts are again concepts teenagers can relate to and enjoy. However, the poem's volta occurs at the very end, or the last line, of the poem, and demonstrates why teenagers should not pick this path. The people envisioned in the poem are obviously living a rough life with the reference to fighting apparent in the poem, and the hard living as well. Therefore, Brooks ends the poem with "We die soon," which would, hopefully, change any young person's mind about taking this path in life.
Langston Hughes, in "A Dream Deferred," uses comparisons to image what happens to dreams that are not pursued. First, he wonders if it turns into something awful: a raisin in the sun fester like a sore. Stink like rotten meat." This would imply that not pursuing one's dreams is an ugly thing.
