The sheer volume of bullying I’ve experienced through my early years at the hands of boys, all of it related to being “too big” even though I was also often asked if I were a model, leads me to conclude that this supposition is reasonable. Combine that with the sociological components about how women are supposed to keep themselves small and unobtrusive and it’s a pretty reasonable working supposition. If it had happened 3 or 4 times, there might be some doubt. Hundreds of times and it’s not so easy to dismiss.
And yes, you may be excused! 😆
