A true friend will always help you overcome during your tough times. A friend is needed in the hard days not during the times, when you don't need anyone. A true friend is an advisor, honest critic, a person who will guide you based on his experience or best knowledge. A friend who is silent, when you really need advice, is of no use. One should leave him, sooner the better.
In the End, we will remember not the words of our enemies, but the silence of our friends."
- Martin Luther King Jr. (1929-1968)
