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.
special word for friend
Do dosto k dimag bilkul railway k track ki tarah hote he,
jo kabhi mil nahi sakte,
lekin wo hamesha sath sath chalte hue dosti ki gadi ko apni manzil tak pahuchate he.
