Sandra washes with a non-brand, roughly-cut, mottled soap bar.
Rebecca: Funny looking soap.
Sandra: Home-made. My friend makes it. Natural products.
Rebecca: I tried a natural soap once, it melted in the bath.
Sandra: It melts, you have to dry it every time you use it, not easy to use, but allergies don’t bother me now.
Rebecca: Ordinary soaps have chemicals?
Sandra: So they say. But they lather easily, whereas with this home-made soap, suds take work.
It's not a soap commercial.
It's a nice example of women’s talk. The opening challenge swiftly turns into an exchange of information. Shared experience (“I tried it once…”) leads to a discussion of strengths and weaknesses (“…melts…but no allergies…) and conciliatory flavorings ("So they say...").
It’s not to say men don’t follow this pattern too… but…you might expect a bit more jousting and posturing at the beginning.
