What is the meaning of this "go in and out": (from Randall Jarrell’s The Bat-Poet)
The chipmunk said in a pleased voice: "My day." He sat there and listened while the bat said:
In and out the bushes, up the ivy, Into the hole By the old oak stump, the chipmunk flashes. Up the pole. To the feeder full of seeds he dashes, Stuffs his cheeks. The chickadee and titmouse scold him. Down he streaks. Red as the leaves the wind blows off the maple, Red as a fox, Striped like a skunk, the chipmunk whistles Past the love seat, past the mailbox, Down the path, Home to his warm hole stuffed with sweet Things to eat. Neat and slight and shining, his front feet Curled at his breast, he sits there while the sun Stripes the red west With its last light: the chipmunk Dives to his rest.
When he'd finished, the bat asked: "Do you like it?" For a moment the chipmunk didn't say anything, then he said in a surprised, pleased voice: "Say it again." The bat said it again. When he'd finished, the chipmunk said: "Oh, it's nice. It all goes in and out, doesn't it?"
