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.
Hereâs a catalog of the archetypal friends that over the course of a life youâre likely to encounter again and again. The Best Friend: The gold standard of friendships. A best friend listens but never judges, helps you out of a jam, tells it to you straight, and often forgives a debt. Best friends resemble invisible friends in that both are most common in childhood (and may not really exist). The Old Friend: Ideally, a lifelong bond that stirs fond feelings and cherished memoriesâunless youâre a celebrity or out on parole. In reality, most old friendships are embedded in a complex economy of favors.
