Read the passage from "I Know Why the Caged Bird Sings."

Momma said, "Sister, I know you acted like a little lady. That do my heart good to see settled people take to you all. I’m trying my best, the Lord knows, but these days . . ." Her voice trailed off. "Go on in and change your dress."

From Momma’s words, what can the reader infer about the type of parent she was?

She was caring and concerned.
She was cheerful and lighthearted.
She was formal and disapproving.
She was stiff and unaffectionate.
