I’ve never understood the “never seen” argument. I wouldn’t recognize anyone I went to undergraduate, or graduate school by face or by name, and I doubt they would remember me. It has only been 13 years since I left school. I do believe there are shenanigans related to most of his collegiate work though, as pointed out above.
I’m 57 and I remember the names of kids I went to kindergarten with. Everyone is remembered by at least a half dozen people.
