原谅我生性凉薄不喜人群
[yuán liàng wŏ shēng xìng liáng bó bù xĭ rén qún]
It means 'Forgive me for being cold by nature and not enjoying the company of people.' This expresses a sense of self-deprecation or a request for understanding one's aloof and unsociable personality traits, possibly stemming from introversion or past experiences that made such traits more pronounced.
