Raoul: Why the hell didn't we do that?

After Officer Keeney asks what Meg meant when she said "There are three..." on the phone to Stephen before being cut off:
Meg: Look, my husband and I just split up and it's my first night in a new house and I admit I was a little drunk. And the sentence, if you insist on knowing, was going to be, "There are three things that I'll do for you if you come and jump into bed with me right now." Thank God I came to my senses before I said all that, and I hung up so nobody would ever have to know what I was thinking. Unless, of course, two policemen came in the middle of the night and interrogated me.
