Farewell "Sisters"

I recently noticed since Elsa has turned four that she has quit mentioning her 5 dead sisters. Don't be alarmed. If I haven't introduced you, Elsa has/had five dead sisters (imaginary) that she named: Juni, Yuni, Charolette, Pepper, and Nancy. Whenever she was mischievous she'd say she learned it from one of her dead sisters. We thought it was pretty funny. Others were disturbed by it. Well now that they're gone, I miss them and am hoping they pop in to say hi every now and then.
