He was not an unfriendly person. He did not know too many people, but formed a lasting bond with the ones he got comfortable with. He was not anti-social, but preferred to avoid human interaction as much as possible. If given the choice, he would rather read a book than attend a social obligation. He used to see his peers laughing and making merry. Often, he remained oblivious to their presence, at the same time, a keen observer of human behaviour. It gave him more to time to analyze, to introspect, and to improve.
Rather than knowing others, he chose to know himself.
