We judge book by its cover, and by our own perspective. Perhaps we don’t expect everyone to behave the way we do, but we tend to set this particular barrier in between, searching for the beings who are about our standard, which in other words, are the people who can and should be around us. We may be complaining about an individual on how inappropriate his doing is, we could be prejudice when a person has a lower ranking than we are in the current society and we might be criticizing the people who are slightly different compared to most of the human beings. All and all, we are looking for the similarities and compatibility among the crowd, people like us in the form of thoughts and behavior. Hence the saying people alike get together. Perhaps it is just us, or perhaps it is our nature that we somehow not able to accept the differences at times, where we would feel irritated whenever we interact or meet a person who we think is from the outside world. Nevertheless, we are never alone, as they may feel the same as we do, annoyed by our doings which are different from theirs.
