it was a requirement to make the bed when i was growing up but now, when i visit home, i don't make it. weird.
when i was in school, i would have so many visitors that i kept my bed made. i didn't want people to see my room messy nor did i want people to sit on my sheets.
now, i make up the bed sometimes. i calculate how long it will be from the time i get out of the bed to the time i'm getting back in it. if i'm not going to be gone for a substantial period of time, i don't make it--unless i expect company. but, i have satin sheets and a duvet so when i make it, i just pull the duvet and it carries the sheets with it. takes about 3 seconds!
