It is very difficult to get a friend in this world..
we have to coin the word friend-in-law for many of our so-called friends, especially with the spate of friendship in social-media..
But still I do hope that a true friend, if there is one, will not do anything which could not be forgiven..
If a situation has arisen where the question of forgiving comes, the friendship must have lost its sense and content.
Forgiving of course comes for inadvertent and innocent offences.. and if a friend is really considerate, then normally such situations may not arise..
But innocent damages do occur...like Dasaratha killing the only son of a blind ascetic couple and incurring their curse..
