Answer: Tense
Foreshadowing refers to the author giving the reader a hint of what is to come later in the story. This literary device helps build expectations, but also excitement or worry.
In this case, the author gives us a hint that something is indeed wrong with them having to leave so hastily. She also says that they were not aware they were not going to see their house for another decade. These statements are an example of foreshadowing, and they give the poem a tense tone.
