In the beginning stages of any relationship, people are constantly gauging the trustworthiness of the other person by their actions. Once they have built trust and have a good track record than the other person is more likely to take the risk of self-disclosure. Most people are not likely to make themselves vulnerable to others that may use their insecurities against them. When people share personal information with you, it suggests they respect and trust you, a kind of liking that signals your relationship has reached a level of familiarity.

When building a relationship, it’s imperative not to disclose personal information too early before trust and a comfort level is established because it’s likely to scare the other person away. If a person starts discussing what went wrong in their past business relationships in detail during an initial conversation, they’re not likely to get a second opportunity. One sign that the relationship is ready for disclosure is when the other person is sharing personal information with you.

Another way of looking at building networking relationships is to use the metaphor of a bank account. You must first deposit money before you can make a withdrawal of funds. If you attempt to make a withdrawal of an amount higher than what you deposited, you will get a response that notifies you of insufficient funds.
The same is true in relationships; we have an emotional bank account or social currency. If you add positive experiences when the relationship is beginning, you are depositing into the emotional bank account so when you need to ask for something unpleasant, making a withdrawal, the funds are in the account. If you are making more withdrawals (negative experiences) than the amount you deposit (positive experiences) the relationship will go bankrupt (end) because you will be viewed as taking advantage of the relationship.
