This one confuses me.

At a big bank there are thousands of people working there, so it’s pretty easy for everyone to say they just never crossed paths with him. Contrast that with HM, which has about 150 kids in each grade.

I went to a religious school with grades that small and I’m pretty sure I know the name and face of every kid in my grade (and if I’m unsure, 15 years later I still have a yearbook to look at!)

Maybe he figured nobody who actually went to HM would be caught dead living in a district like his?
