Later that night，her daughter attempted suicide.

　　In the days that followed，it came to light that she'd hidden herself in her dorm，crying and showing signs ofdepression-a completely different reality from the one that she conveyed in text and Facebook posts.

　　As human beings，our only real method of connection is through real communication.Studies show that only7%of communication is based on writing and spraking.The ma jority of 93%is based on body language.Indeed，it's only when we can heard a tone of voice or look into someone's eyes that we're able to know when'I'm fine'doesn't mean they're fine all.

　　This is where social media gets risky.

　　With modem technology，anyone can hide beind the text，the e-mail，or the Facebook post，projecting any image they want and creating a false image of their choosing.They can be whoever they want to be.And without the ability toreceive body language，their audiences are none the wiser.

　　This presents a paradox which doesn't exist before.With all the power social technologies at our fingertips，we are more connected-and potentially more disconnected-than ever betore.

　　Every relevant metric(衡量標準)shows that we are interacting at a great speed and frequency through social media.But are we really communicating?With 93%of ourcommunication context(語境)lost，we are now attempting to establish relationships and make decisions based on phrases or emoticons，which may or may not accurately represent the truth.
