Munching a plum on
the street a paper bag
of them in her hand

they taste good to her
they taste good
to her. they taste
good to her

you can see it by
the way she gives herself
to the one half
sucked out in her hand

comforted
a solace of ripe plums
seeming to fill the air
they taste good to her

in "to a poor old woman," how does paper bag full of plums act as a symbol?

it represents the simple pleasures that make life worth living, which give the poem its positive tone.
it represents the mundaneness of everyday experience, which conveys the poem's indifferent tone.
it represents the limits of human happiness, which stresses the poem's fatalistic tone.
it represents the great luxuries that people experience only occasionally, which develops the poem's awestruck tone.
