In society, it is almost impossible for people to leave the group and make friends.
The above "sentimentality is detrimental" refers to the degree of investment (affection) in making friends. Maybe friendship is not particularly beneficial in your sign. Therefore, I hope you make friends carefully, and you can't be affectionate, affectionate and emotional to anyone. Make friends selectively.
"nip in the bud" means that it may be unlucky to bump into each other, and it is inevitable that friends will cross and use the wrong feelings. However, we should learn from the past.
Confucius could not educate his disciples by "never passing" and "never venting". You may be sentimental, but you should wake up after the injury.
