When I was in 4th grade, the school nurse called me into her office and told me I needed to start wearing a bra. In my memory, there was another (male!) student in the office in earshot and I was super embarrassed. I remember her doing this kind of loud stage whisper, so I'm sure the other kid heard it. It had never even occurred to me to start wearing a bra because I didn't really have breasts yet. It being the '90s, all I wore was oversized t-shirts and leggings, and I guess someone might have caught a glimpse of my chest at some point. This was quite traumatizing at the time, and one of the few memories I have of that time in my childhood. My question is, what the hell? Is this a common practice? And if it is, for heaven's sake wait till there are no other students in the office to tell a pre-pubescent girl she needs to wear a bra!
P.S. I should add that I have always been like 99th percentile in height and by the time I was in 4th grade I was probably at least 5'5 or so, so I guess I must have looked more like a grown up woman than I actually was, but I definitely did not have breasts, either.
