...by the time I was 8. We had to make our beds every morning before leaving for school. Beds were also changed once a week before going to school.
In 5th grade, I missed out on something I dearly wanted to do because of this damned bedmaking routine/ritual. 2 of my classmates, one boy and one girl, had been chosen to be the flag kids that year - raise it every morning, take it down every afternoon. The guy was a cute redhead, and was my first crush. The flag girl was going to be absent one day, and I was thrilled to be picked to take her place and get to do the flag duties with the cute redhead. It never happened, because that turned out to be bed changing day, and my mother absolutely would not deviate from that plan even tho I explained why I wanted to leave early for school that day, and pleaded for her to relent. Nope, no way. I didn't get there on time. I was crushed.
I became a nurse too, and made many, many beds before transitioning to the nurse practitioner role.
Some years ago, we stayed in a small hotel near Spangdahlem, Germany, while visiting my husband's older son, who was stationed there with the Air Force. During that trip, I learned that it was customary there not only to leave the sheets loose at the foot of the bed, but to turn the duvet down all the way to allow the bedding to air out. So fast and easy, and, if you like pretty sheets, as I do, you get to see them instead of covering them up with a bedspread pulled all the way to the head of the bed. I've done it that way ever since.
