The correct answer is going on a first date.
This Gary Soto’s poem, Oranges, describes the feelings of a boy going on a first date, most probably, for the first time in his life. That is the reason why we can say that the poem depicts a rite of passage, because this was a significant turning point in his life.
The first date is described as the first time he walked with a girl. He picks her up. She is wearing make-up. The physical contact between them is shy and gentle and he leds her down the street. He invites her a chocolate bar and the poet keeps on describing his thoughts an feelings to vividly recreate that passage from being a naive boy to a hormonal teenager.
