Why do people sleep on beds?

<p>Just curious, S-O-1700...but if you heard this:</p>

<p>*"My wife's on vacation in the West Indies." </p>

<p>"Jamaica?" </p>

<p>"No, it was her idea."*</p>

<p>Would you reply: "Well...the question was about the place they went on vacation, not who wanted to go."</p>
