The mobile phone has become a formidable "secret" weapon for teenagers. I find this quote from the book I'm reading (about China's Gen Y) amusing.

"So there are some things that you can talk to your parents about, and some things that you can't. So what can you talk to your parents about?"

"My cellphone fee."

And the cellphone is used to talk about things that he cannot tell his parents. The irony of things.
