We go to meet somebody at his/her house and become very happy after coming back thinking that "oh we have maintained the relation ship".But now the time has come,to please judge before going to somebody that whether the person likes your visit to his house/residence or not.Or he/she has called to insult you at his/her home.If so,then we should not go.Such relation ships are forceful and must not be maintained,in this world of jealousy and complex thinking.I think Muslims are far far better in this respect than hinus as they never keep barricade of status between friends/relatives and be always satisfied and proud of their status whatever it may be.Another thing the curtain system(i.e.Parda System) between males and females is also appreciable to some extent ,if it is not too much..
