It is the multiple relationship.
A good friend is that who always with you ,your good or bad both situations . and suggest you to what's the good or bad for you . they internally knows you .
They feel you, they never jealousy with you . they always support you. Pure hearted .a story like a tom and jerry,they fight each other but they can't live without each other .
FRIENDSHIP are such a beautiful things .it is where one soul trusts another to find comfort zone and libration on this journey .
Thank you ....
