As is often the case，when people are attending meeting，having meals or waiting buses，you can always find them addicted to their phones，complete ignoring others．
This is really a common phenomenon in our life．The reason is why smart phones nowadays can be used for people to play mobile games and kept in touch with friends through QQ and WeChat．Besides，too much exposure to phones are bad for people in terms of health．Moreover，people involved in phones fail to communicate good with those around them．
