EMILY: Richard, perhaps you could get that while I have another bath sheet versus bath towel debate with your mother.
Bath sheets are simply large towels – large enough that you can wrap them around your torso or waist after your bath or shower. They are efficient for drying as they can soak up more water, and are seen as the luxury option. However, some people find them too heavy and cumbersome (and take a long time to dry out). It is unclear whether Trix wants a bath sheet rather than a bath towel, or the other way around.
