Looked through the list of photos.
None of the women were either ugly or unshapely.
They didn’t look like they needed to go after the younger set for comfort or excitement.
A lot of teachers in general (yes, I’m painting with a broad brush) can’t deal with adults. Never mind the worst-case scenarios (sexual assaults of minors); how many people have met with teachers and have had them try to address only the mother when both parents are present? It seems many people who want to hide from reality find places in the education industry; the public school systems provide generous pay & benefits for 180 days per year (and those days aren’t 9-5), and the “employment for life” is particularly attractive to them. It just leaves them isolated in their own world, unable to relate to anyone in different circumstances.
As with roles in religious or scouting organizations, people are slow to realize sexual predators SEEK this work.
