One of the simplest determinants of interpersonal attraction is proximity. The people who, by change, you see and interact with most often are most likely to become your friends and lovers. The finding that the more we see and interact with people, the more likely they are to become our friends. The propinquity effect works because of familiarity, or also known as: The finding that the more exposure we have to a stimulus, the more we like it. We see certain people a lot, and the more familiar they become, the more friendship blooms. Of course if you feel negatively toward the person in question, then, not surprisingly, the more exposure you have to him or her, the greater your dislike. Propinquity may soon no longer be a prerequisite for the formation of relationships. This is due to the existence of online communication via messenger or dating website or via phone.
