“Here, deares’.” She groped around in a waste-basket she had with her on the bed and pulled out the string of pearls. “Take ’em down-stairs and give ’em back to whoever they belong to. Tell ’em all Daisy’s change’ her mine. Say: ‘Daisy’s change’ her mine!’.”
The problem with Daisy is that she is a gold digger. She is only after the money. It's unfortunately something most girls were after around that time. However this would only be the case when she would be sober; but on the flip side, when she is drunk, she wants to change her mind and marry the guy she actually loves, which causes her to give the expensive string of pearls back.
