New preprint out with a longitudinal study of two years of a high school. Key findings:
* Further evidence of the existence and relevance of Dunbar's circles
* There are many less enmities and they are highly volatile
* There is an almost constant degree of reciprocity in the relationships, around 60%
* The whole social structure is very robust even under the huge perturbation of covid-19
