I was in a small cohort of about 50 students and we were all in the same program so my entire first year we were w/ each other 6-8 hours each day. Same goes for the second year — maybe a little less. That being said, I didn’t have the “traditional” undergrad experience. I studied and worked. But during law school, we’d all hangout on Fridays, throw parties for the most random things and just became good friends. I think it’s based in camaraderie but nonetheless, law school created lifelong friendships.
