What was the mother's attitude towards Polly's and Matilda's desire to attend the funeral?

Mother refuses to allow Matilda to go to the funeral because it would give her nightmares. It was Polly's funeral.

“I’ve already paid our respects,” Mother said. “You’ll just upset her mother more. I’ll take a food basket there myself. Tomorrow. Now put on a clean apron, Matilda, and wash your hands. It’s time to get to work.”

“I want to see her!”

“No.”

“What about the funeral?” I asked, blinking back the tears. “You must let me attend that.”

“No. Absolutely not. I forbid it. You’ll have nightmares.”
