Looking at my own experience, I didn't even particularly like my friends when I first met them. Several of them seemed outright repulsive. It took several months of being in the same "sticky" social situation to bond--long periods of time in the same school, sport, club, neighborhood, etc. If I had the opportunity to transplant myself into another social situation after the first day/week, I'd never have made any of those friendships.
How can we keep the same group of people stuck together for a sufficient amount of time? I think that's the secret for creating friendships and curing loneliness.
