Overall, the ability to consider others and be concerned about their needs is a quality that is quite wonderful to have. However, when we always push the same character quality to the front of the line, the virtues of listening, empathizing, and supporting quickly turn into the character defect of care-taking behaviors. In the end, care taking is not only unhealthy for you, but for the other person too. For instance, Kalie's friend Dana didn't need another friend to gratify her narcissistic needs; she needed a friend who would confront her behaviors, offering her a chance to look at herself and grow.
