I didn't have daytime control until halfway through second grade, so I frequented the school nurse's office for diaper changes. I do remember getting changed a few times by a friend of the family on whom I had a crush. She was helping in the office and changed me while the nurse was busy with another student, who wasn't there for a diaper change.
Nighttime control didn't come until the end of my fifth grade year. Sleepovers were few and far between, and I was always diapered before bedtime.
Fast forward 28 years, and I have no daytime or nighttime control due to bladder cancer diagnosis seven years ago. I don't want to wear a diaper all the time, but it is the only thing that works for me right now.
