Based on Fredrickson's ((1998 Fredrickson, BL. 1998. What good are positive emotions?. Review of General Psychology, 2: 300–319. [Crossref], [PubMed] , [Google Scholar]).

New York: Hemisphere) self-expansion theory, it was hypothesized that positive emotions broaden people's feelings of self–other overlap in the beginning of a new relationship. In a prospective study of first-year college students, we found that, after 1 week in college, positive emotions predicted increased self–other overlap with new roommates, which in turn predicted a more complex understanding of the roommate.

Implications for the role of positive emotions in the formation of new relationships are discussed. At such moments, you realize that you and the other are, in fact, one. It's a big realization.
