孤独成性不过是厌恶人心淡定窥世不过是心灰意冷
[gū dú chéng xìng bù guò shì yàn è rén xīn dàn dìng kuī shì bù guò shì xīn huī yì lĕng]
It roughly means 'Being accustomed to loneliness stems from a dislike of the pretentiousness in people, and calmly watching the world stems from feeling utterly disheartened.' It reflects a person who has withdrawn from society because they are tired of the hypocrisy and superficiality they perceive around them.
