This topic is broadly discussed among the young in China.
You can call it an Internet phenomenon.
You can see as below everywhere on the Internet:
"Too sweet to have friends. Too smart to have friends. Too beautiful to have friends."
Sounds like a bloody curse, isn't it.
Well, my roommates take it as a fashion.
And expressing:"Oh, I don't have friends!" ,which implicates that" I am not that smart, cute or beautiful to be a threat to anyone. I am not outstanding, just like other normal 1.3 billion collectivists in China."
"I don't have friends" becomes a new sick way to show modesty.
