In the first paragraph of Sharon Creech's Walk Two Moons, the narrator, Sal, says that she has lived most of her thirteen years in the countryside. However, she continues:
Just over a year ago, my father plucked me up like a weed.
This simile suggests that Sal was an inconvenience where she was. Flowers are also plucked, but the purpose of plucking flowers is usually to display the flowers or give them as a gift. Weeds are plucked to be thrown away. When she reaches her destination of Euclid, Ohio, Sal describes her new urban environment. There are no trees on the street, and the houses are right next to each other.
The houses were all jammed together like a row of birdhouses.
Sal thinks of the city in terms of things she already knows, and birdhouses are the only houses she has ever seen that are as uniform and cramped as the ones in Euclid.
A third simile in chapter 1 is extended, and takes several paragraphs to explain. Sal says,
I realized that the story of Phoebe was like the plaster wall in our old house in Bybanks, Kentucky.
She explains that after her mother left, her father kept chipping away at the wall. When he heard that she was not coming back, he pounded at it and eventually uncovered a brick fireplace. Sal says that her own story is hidden beneath Phoebe's story just as the fireplace was hidden behind the wall.
