Why do we always aim the sharpest words at the people closest to us? It's because only those closest to us have the opportunity to accumulate prejudices. As for those with whom we have little interaction, it's very easy for us to show the noble side of our character. Prejudices stem from trivial matters in daily life. It could be just an unpleasant conversation or a disagreement over a travel plan. These minor differences in opinions can directly affect our subconscious minds and lead us to accumulate prejudices.
For example, at work, we tend to reject the requests of colleagues we don't like, even when those requests are reasonable. In an intimate relationship, we might oppose any small suggestions put forward by our partners later just because of a previous quarrel. In the family, we may gradually become silent due to an unpleasant communication, even if the other person has the right to know certain thingsSimilarly, this kind of prejudice is mutual. In an intimate relationship, both parties with prejudices against each other will feel terrible, because the source of prejudice is based on facts. That is to say, the more prejudices the other person has accumulated against us, the more we will feel completely exposed. And at this time, the person who feels exposed often needs to find a relationship without prejudice to make themselves feel good. That is, they may have an affair.
