>In school, or college, it was easier to be in proximity to other people which is just not possible as an adult. I think it is more that you made friends with people that already lived near you (ie the kids going to your school). As adults, the only people that match a similar profile are your work colleagues but adults tend be more closed off to making friends. In some cultures, it is still easy but north european cultures seem to make it so that when you reach some age you close off to new people.
