in line 96-97 underline what mama says she will do after maggie marries john thomas? how does mama feel about maggie

After Maggie marries John Thomas, Mama will be free to sit and sing without an audience.

She will marry John Thomas (who has mossy teeth in an earnest face) and then I'll be free to sit here and I guess just sing church songs to myself.

Mama loves Maggie more than she can say, but more importantly, she feels a fierce protectiveness for the daughter who is unable to protect herself.
