We cannot tell the precise moment when friendship is formed. As in filling a vessel drop by drop there is at last a drop which makes it run over, so in a series of kindness there is at last one which makes the heart run over.
Dard jitna saha jaye utna hi sehna,
Kisi ke dil ko jo lag jaye vo baat na kehna,
Milte hain hamare jaise dost bahut kam,
Isline humse "Kabhi Alvida Na Kehna"
True friends are those who are there for you unconditionally. Never do they question, but always offer support no matter what the circumstances are. Best Friends are the people worth living for.
