If you want to engineer the possibility of growing a relationship from a casual connection into something substantial, you need exposure. Research shows that the more exposure we have to something, the more we tend to like it. Known in psychology as the propinquity effect, this tendency explains why you grow fond of someone you spend time with even if, on paper, you wouldn’t necessarily have chosen that person as a friend. The more time you spend with someone, the more likely it is you’ll connect.
