Companions are great as long as they know when to keep quiet, and it's good if they have their own hobbies too...which women, in my experience, rarely do.
(NOTE: Before anybody reports my "misogyny", I HAVE known women who had hobbies like photography, journaling, gardening, drawing and painting, designing and sewing custom clothing, and even one girl who worked on her own 911 and actively competed in solo SCCA events...but they are few and far between; simple truth.)
