Friends are the spice of life. They are our rampart in times of distress, the confidante to our innermost thoughts, and reinforces us in times of weakness. Of all the people we know throughout life, there are only a few that fits the bill. An even rarer find are your true friends; those that do not leave you even when things get really tough.
What makes someone a friend? How do they stand out from the rest of our acquaintances? Seneca, in his letter On True and False Friendship said that the crucial element is trust.
