How does Alice Munro use imagery in Friend of My Youth: Stories?

"You see them going around with notebooks, scraping the dirt off gravestones, reading microfilm, just in the hope of seeing this trickle in time, making a connection, rescuing one thing from the rubbish." (Meneseteung, p. 73)

"You can look down a street, and you can see the shadows, the light, the brick walls, the truck parked under a tree, the dog lying on the sidewalk, the dark summer awning, or the grayed snowdrift - you can see all these things in their temporary separateness, all connected underneath in such a troubling, satisfying, necessary, indescribable way. Or you can see rubble. Passing states, a useless variety of passing states. Rubble." (Oh, What Avails, p, 208)
