Sonia Harcourt is delighted because her stepdaughter, Madi Collins, has returned home for a visit after her first semester at college. Madi talks about how interesting college life is, and how it's a whole different world from what she's used to. In fact... she has some questions. Sonia encourages her to go ahead and ask, so Madi says that her college roommate has a girlfriend. The roommate and the girlfriend are both very nice people, but Madi is confused about how their relationship works, because the only sex she's heard of involves girls with guys.
