People of different types live in one place and wonder why others are not like them. They have different tastes and desires and wonder why other person does not exhibit the same type of attitude and behaviour as they used to show. People have this same question all ways in mind , they try to understand and try to misunderstand others, and find joy in doing so.
People all ways find joy in underestimating others, and find elevated by showing their bit of knowledge which is superior to others. This is far visible more in religious wisdom just like any discipline or subject, or politics or whatever it is. People find its great to show their wisdom more superior to others. and thus learn to look down at others who are lesser in knowldege.
Not knowing that every one has a talent or potentiality which cannot be compared with others, even in this field they do face competetros. who would beat them out.
