What is mr smiths reaction to her plan

There is no Mr. Smith in this story.

Idk what the answer is

True, they are not the Smiths, they are the Whites.

Mr White vehemently opposes his wife's plan to use the paw to bring their son back to life, but he allows her to do it anyway. Unfortunately, Herbert appears on their doorstep like the "undead," and Mr White makes a wish of his own.
