I believe that for a friend to be considered REAL are those who never leave us in times of difficulties especially when we are troubled with problems... financially or emotionally. We tend to appreciate the friendship more if they are willing to share their presence and care to listen... just be there to listen.
Trust is earned not given. This same trust will strengthen the relationship. It grows through the years of unselfishly offering a part of one self for the happiness of others.
When is friendship being tested? This is a question of what goes wrong... or who faltered. Once a glass is broken, it cannot be fixed. There's a mark of betrayal and dishonesty.
