In Anne of Green Gables by L. M. Montgomery, Marilla criticizes Anne for talking too much:
"Well, I guess I'll light the lamp and get to work," said Marilla. "I see plainly that you don't want to hear what Miss Stacy had to say. You're more interested in the sound of your own tongue than in anything else."
"Oh, indeed, Marilla, I do want to hear it," cried Anne contritely. " I won't say another word — not one. I know I talk too much, but I am really trying to overcome it, and although I say far too much, yet if you only knew how many things I want to say and don't, you'd give me some credit for it. Please tell me, Marilla."
What does Anne mean by "give me some credit"?
