“Sociologists since the 1950s have considered repeated, unplanned interactions in a setting that encourages people to let their guard down and confide in each other as important to the formation of friendships,” said Dr. Rebecca G. Adams, professor of sociology and gerontology in the School of Health and Human Sciences at the University of North Carolina, Greensboro.
“High schools and colleges are, for example, breeding grounds for friendship because students who attend a given institution usually have a lot in common.”
