I never do. But I have a really good reason! DH works nights and I work days. Someone is sleeping in the bed 20 hours a day. There is no point in making it! I do straighten out the sheet and blankets as I'm getting ready for bed, DH always makes a mess of them while sleeping, but I don't do a perfect job, I just untangle them and retuck if needed. I hardly move so the bed is "ready" for him when he gets home and I get up, he doesn't have to do a thing!
