As you will grow and will discover the crualiy of this materialistic world. You will come to know about the truths, There are two types of relatives. Initially very hard to distinguish as we are all innocent by nature at start. Once we grow we see the two types.
Type1 are those who demand relations. By default they think that the relation is not good. You have to call, ask the questions, enquire about their health etc. If you do not do that they think there is some problem. Or you are not good. Or your behavior is not well. Un-social.
Type2 are those who command relations. By default they will always be positive with you. You do not call them for a year, this will not change their mood. They will never complain.They will genuinely help you in terms of money, resources, tenderness. You can read the eyes. Eyes never lie.
Beware of Type1. Selfish, complaining, irritating people. You should be starightforward to these people. For Type2, they are good, you need to nourish the relationship strong.
