rectangle time：矩形时间
什么是“矩形时间”？
聚会或饭局上低头看手机原本是不礼貌的行为，但是随着越来越多人开始享受这种人群中的“独处”，社交时间也慢慢被“矩形时间”所蚕食。“矩形时间”指人们在社交场合选择拿出智能手机，和自己的“矩形”独处的时间。
Rectangle time is the time of day when people in an obviously social setting instead choose to pull out their smart phones and have some time alone with their "rectangle". The term can also apply to other electronics, such as computers, iPads, etc.
