Any relationship can turn out to be the best if it includes the aspect of letting each other to be sometimes stupid, sometimes act funny and most importantly allowing each other to be himself/ herself. It is not about judging or wearing a mask everytime. Infact, in simple words...it is about being "Natural"....Sooner or later..everyones' mask falls off..So , it's appropriate to be natural from the beginning itself . It's not about compromises enforced but about compromises accepted and made willingly....It is not about changing by coercion but changing willingly for eachother....(that in simple words mean overcoming the vices of oneself for eachother). It involves the acceptance in an original way but doesnot involves the efforts regarding changing eachother for one's own benefit.
Also, it not only involves the element of speaking but also of listening, strong communication...sometimes understanding without communication (Telepathy), respect , care, honesty, standing by eachother, forgiving, protecting eachother, making eachother feel happy, not to intentionally make the individual feel bad and not to unnecessarily curb the individual's freedom/space.
God has given us a range of relations to experience and cherish in one life...isn't it great?...Each relation of every human being has it's own beauty and is not be compared with one another. Any relation solely depends upon two individuals. Therefore, the above stated elements can be used by individuals to make their relations "best"...I think all of us ....owe atleast one best relation and therefore, should also work hard towards not losing it and maintain it with dignity throughout our lives.
