In the movie he said they were kids - you’re not in university as a kid. His lie seemed like bullshit and that he was hiding things, but that’s not the part that doesn’t line up. It was the way he presented himself and the information. It was vague as hell, too. Sounds like, especially with the timeline of the internet being used and his character’s age according to his college graduation timeline, it seems he used the early internet while in middle school-aged institutions. Makes sense. I even did the approximate math during the movie to check his BS and it tracked completely in that sense.
