Let me see. Somebody, probably the old and sickly woman, criticized Eliza's laundering. Meanwhile

Do you like the music of the church, Eliza?
Does the minister give intelligent, helpful sermons?
Do you have friends there?
Does the church do good works for those who need help?
Are you turning your back on a lot of people trying to do right because one person was silly?

Go get the ax; there's a flea in Lizzie's ear.
