Debs is having an affair with a married man. Not that she meant to, or anything. But while she was miserably hanging around waiting for Mr Right -- is it her laugh? Her thighs? Bad breath? -- Bob just kind of happened. Lovely, kind, sexy Bob. Who was also a rampant cheat, but so long as his wife doesn't find out then Debs isn't hurting anyone, right? Cleo is married to Bob. She also thinks he's lovely, kind and sexy, even if the last bit has worn a bit thin after fifteen years of marriage. And two kids. And the horrible sound he makes brushing his teeth in the mornings. But that's the reality of marriage for you, and she can live with his silly little affair so long as it doesn't interfere in her life. So for now it's just the three of them -- but how long can that last?
