Donald tells Ann that if she wasn't in his life, he probably would have worked this weekend. As such, Ann does allow Donald to live his "without her" life, as she decides to head back to Brewster to visit with her parents for the weekend. But that plan doesn't come totally to fruition as Lew and Helen are heading into the city for the weekend for a convention. So Ann is left to her own devices at her parent's house. When she isn't fondly and not so fondly reminiscing about her growing up period in Brewster, Ann, who has too much alone time on her hands, hears every little proverbial bump in the night. Those bumps do cause Ann some grief, but probably not quite in the way she initially suspected.
