Social penetration theory posits that there are two dimensions to self-disclosure: breadth and depth. Both are crucial in developing a fully intimate relationship. The range of topics discussed by two individuals is the breadth of disclosure. The degree to which the information revealed is private or personal is the depth of that disclosure. It is easier for breadth to be expanded first in a relationship because of its more accessible features; it consists of outer layers of personality and everyday lives, such as occupations and preferences. Depth is more difficult to reach, and includes painful memories and more unusual traits that we might hesitate to share with others. One reveals itself most thoroughly and discuss the widest range of topics with our spouses and loved ones.
