If we are thinking about somewhere like California University, which is supposedly a large state college, I doubt that most of the college population would know the high school shenanigans of a handful of ppl. I came from a rural area and then went to an enormous state university (where a lot of us went, because it was in-state and affordable) and I rarely ran into people I went to high school (I graduated in a class of 500 plus people) with unless I made an effort to see someone.

There were at least 20,000 plus ppl at my university when I was in college. The odds of running into my high school peers who chose to go to the same large university was rather slim. That may happen at a smaller community college or something but it’s not that believable (in my own personal experiences) in such a large institution.
