1 When you fall on hard times, a good friend is loyal to you. As the saying goes You know who your true friends are in hard times.  A good friend is sensitive to your needs and can be sensitive when the situation requires it.
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.
