I sleep with my blankets loose (as in, not tucked into the bed itself), so they basically just sit on top of my bed in whatever way they were when I got out of bed. I never tuck them in/make the bed. My mom used to/tried to get me to do it but quickly learned that I will never sleep in a made-bed, and qill quickly unmake any bed I intent to sleep in.
I don't make my bed unless you count me making the blankets spread over me while lying in bed. I see no point in it, its going to get messed up again any ways. and I don't make the bed after laundry as I never put sheets on to begin with as I have a habit in my sleep of taking the sheets off.
Okay, then. If you mean make the bed AT ALL, ever, then I'd say most people do so in some situations. I personally wouldn't bother unless I was concerned about company seeing the bed, for instance.
From what I can tell, most people are pretty much like I am, except that they also make the bed out of habit when they first put the sheets on it... but then unmake it when they sleep in it, and leave it unmade until they change the sheets again.
So technically they DO make the bed sometimes, but they don't keep it made.
I wish I had more options than just "yes" and "no," but I have to go with "yes" on a technicality if I'm being forced to choose.
