Arngrim described the first time she met Anderson on the set of Little House on the Prairie in her book Confessions of a Prairie B****. They were getting ready in hair and makeup. According to her, Anderson wasn’t warm. Arngrim says there was a quality about her that seemed rehearsed, much like a “beauty pageant contestant.” Arngrim says when they first met, Anderson “narrowed” her eyes at her and gave her an “artificial” smile.
