Non sequitur

I can tell the ceremony is getting close. While watching Desperate Housewives last night Kelley randomly asked me how I was going to wear my hair. Any other time I'd reply, "when?" But I know to fill in the blank with "at the wedding." Other variations of this question include: What are you going to say (at the wedding)? What are you going to do in the morning (before the wedding)? We're going to need some private time after (the ceremony). And, whose going to watch Judy (while we're having some private time)?
