Played as a cynical, sharp-toungued, hard-working, sassy but caring and responsible housekeeper, in her late 50s or 60s, Berta takes great joy in making fun of the Harper family for their faults as they amuse her. She often puts in good quips to conversations they are already having, ending or extending them. She strikes fear into the hearts of others simply by giving frowns. She does have a sense of decency and disgust, making her willing to leave the house when something is happening.
