How does the author use foreshadowing in My Darling, My Hamburger?

In Chapter Three, the author uses the literary technique of foreshadowing with the topics of Sean's obsession with suicide and the incident where Sean narrowly misses hitting the rabbits on the road. Death of spirit as well as the end of a life will become important by the end of the novel, and the author illustrates how obsession and fear can be fully realized by decisions and fate.

There is also foreshadowing in Liz's astrological reading, which states, "You are a selfish, passionate individual who hates with the strength of a scorpion's poison and loves with the madness of a gypsy. It is in your nature to steal, and unless you pray to the Madonna you will be punished for this sin as well as your sins of omission. You embrace life with gluttony, and unless you control your appetite you will suffer much pain. One day you could murder. Pray to the Madonna. On Sundays pray to the Madonna. Pray that God will forgive your lust." The very nature of horoscopes is future-focused and this one will prove to have major significance in Liz's life in the very near future.
