But we allow good relations to fade.

Relationships matter for humans.

Humans love to be together. We live together as spouses, siblings, parents, teachers, colleagues, students, teammates, juniors, and with a variety of other tags. 
We are living together based on birth, marriage, occupation, ideology, security, mutual benefits, morality, boundaries, and some other grounds. 
Our identity changes as we age and enter new positions. We adapt to new responsibilities. Initially, matter moves smoothly but often fades over time. 
As a pattern, old relationships start losing their glow when dependence shrinks and responsibility changes. Nevertheless, outstanding memories, sweet or sour, are retained. 
I tried to know why I am distracted in relationships that are made to be strongly attached, irrespective of place, position, and sensitivity. Reasons are not uniform, but ten prominent facts, I am sure, are curves of relationships. 
■ Feelings of closeness 
I have seen the feelings of one individual about another change gradually, even though there is nothing wrong on either side. As if feelings also expire. Old relations are sidelined when new ones emerge from marriage, change of occupation, migration, earning power, and so on. Even without valid reasons, people get less connected as time passes. 
■ Expectations
Too high expectations from anyone see distractions, sooner or later. A father expects too much from his son emotionally, failing which son loses that degree of affection from his father later on. As scenarios change, expectations become illusions.
In many relationships, things are taken for granted. In cases of breaches in granting such helping hands, people start losing faith in each other. 
■ control
The habit of controlling everything creates distance in relationships. People prefer to create their own space as they grow, and any interference leads to cracks in relationships. A retired individual who was in an honourable position for decades takes time to settle into a new status. An insincere student turns professional, goes on controlling things, and staff recognize him as a taskmaster. They unwillingly work together. 
■ Unfairness. 
We all like fairness and honour wherever we are—home, office, society, or something else. When sincerity is manipulated for disproportionate advantages, relationships are likely to go awry. 
"The toxic dance of control and manipulation leaves scars that are invisible but excruciatingly painful." Rachel Stevens 
■ Silent blame. 
In blooming relationships, all is fine. It then goes down to reality. It goes further down to fault findings. In this downfall, relationships either end or remain threatened. 
"Problems in relationships occur because each person is focusing on what is missing in the other person." Wayne Dyer 
■ Assumptions
When there are deficiencies in trust, we start assuming many things, mostly without any evidence. Wild assumptions damage the relationship, eliminating the chances of getting it restored. 
■ Inwardness
When matters degrade, all goodness in relationships seems to shift to playing tricks. We forget to look inward—our faults. If the habit of telling lies is a source of bitterness, we never admit it. Rather, the erring person protects it with might. 
"It is not the mountain we conquer, but ourselves." Edmund Hillary
If someone is not on the right track, then it is difficult for him to maintain good relations. 
Selfishness is like a toxic element in our relationship. People can bear your indifference, laziness, and haphazardness, but not your selfishness. So relationships decay. 
We consume our time correcting others without knowing that we are living with similar deficiencies. This is a common drawback. 
■ insecurity
Security is our primary concern. Ancient people were in groups just to ensure their security against beasts or other dangers. When we feel threatened, whether real or imagined, we avoid mixing freely, even with known figures. We start doubting and staying in closed surroundings at the cost of losing good friends and decent locations nearby. 
Insecurity dominates over intelligence and fraternity. 
■ Emotions 
Emotions play a greater role in living spaces for all of us all the time. While coming closer to my college after four decades, the same feelings got ignited about landscapes, trees, and buildings. 
Emotions have two faces. Emotions of love with anyone or anything keep us close, while emotions deprived of love are unstable and diminishing. 
■ Sacrifice
In any relationship, some amount of sacrifice and compromise are a must. Many relationships get distorted because one or both sides are averse to sacrifice, reluctant to forgive or forget and avoid the opportunity of compromise for larger and longer interests. 
Conclusions
Keeping all relationships on the same scale of love, affection, experience, and respect is not possible, but good relationships must not be allowed to fade. 
Good relations are as important as good health. 
People are irrational, which does not permit us to be irresponsible. 
Be good, as nature favours goodness. 
In the present set of things, people are well connected, at least on the phone, which has made the task of keeping relationships open too easy. 
Being humble in relationships is rewarding forever. 
Leave the place, but do not forget to give people good memories as your invisible assets.
