I went to boarding school my last 2 years of high school and lived on campus my first 2 years of college. The high school experience was even more intense than college. The high school was very small, ~400 students vs. 10,000+ students at college. So, you literally knew everyone at the high school.  I haven’t seen most of my high school class since graduation but I still love and miss them all, even the couple of assholes.
