This shows that she didn't even ask to come with and made her own dissection to come with this show that she is careless.
I know this because the text says, "Wait" the girl said "I'll come with you." Just like the she said it, as thought she'd been invited."
The conflict of the story is that Risa invited her self to go and see Mrs. Benson
In the story heather is starting to become jealous of Risa and how she is better than her at some things.
The text says, “What a wonderful idea!” Miss. Benson said. And it was a wonderful idea. I wished I’d thought of something half as wonderful. Though Miss. Benson seemed to like the story I’d read well enough."
How the characters act
This quote is showing that Heather is getting jealous because she came up with a better idea than she did.
The text says, "Suddenly I could see how scared she’d been, scared for the baby, scared to go off and leave her brothers, probably scared to walk into a strange doctor’s office alone too. “Here,” I said, moving toward her. “Let me take him. Is he going to be all right?”"
The theme is that you should never judge someone by how they look or how they first act.
This show that Heather is realizing Risa is technically a mother to her brothers and that she has a lot of responsibilities and that she is not just this annoying girl that she thought she was.
