Friendship is based on forgiveness.
Today if your friend has done something wrong,
you have to forgive her immediately by thinking that you could have made the same mistake.
If she has been nasty to you today, you have to forgive her immediately.
Tomorrow you may be in the same position - you could be nasty to her.
So if you forgive her when she is nasty, then if a day comes when you are equally nasty, she will forgive you.
Good qualities eventually come for ward. Good qualities will not remain dormant forever and forever.
