How do you leave your bed in the morning...and WHY?

I am amazed at my SINGLE friends, who expect NO ONE over and yet have their beds made up as if in an magazine ad, while other people, married/kids, etc, and maybe even expecting guests, have their beds in a total crumpled mess with piles of stuff on it, as well.

Remember, this is for those who LIVE ALONE. How do you keep YOUR bed looking when you leave in the morning?
