1 A good friend is sensitive to your needs and can be sensitive when the situation requires it.  A good friend is not afraid to give you candid feedback since they know it will benefit you and you have the respect to offer the feedback.
A best friend is not only someone you have a good time with, it is also someone you believe you can trust your life with. A best friend is the first person you call when the most amazing things happen in your life, and when the most horrific incidents happen. A best friend is the person you will always remember no matter what comes about.
