（S：我發覺我有些「朋友」，真的很差。有次我和一大班朋友吃飯。其中一個朋友和我高談闊論，他工作中有趣的東西。當他講完後，我就想講同樣的話題。我企圖講，我在工作所遇到的問題和解決方法。當我第一句還未完成時，他竟然用粗言穢語說：「甲乙丙我就懂。」示意他不想聽下去。）
你在平日就需要有心理準備，最壞的情況是，自己沒有朋友。有時，為了維護自己的尊嚴，要寧願沒有朋友。害怕孤獨的話，你就會不自覺地，接受了一些，沒有絲毫禮貌的人，做你的所謂「朋友」。最大的問題是，大部分情況下，你對一個品德差的人越好，他反而會對你越差。

Wave function collapse is a process of losing the superposition information to the environment.
The remaining problem is that we still cannot predict which part of the information will be lost.

In quantum mechanics, quantum decoherence is the loss of coherence or ordering of the phase angles between the components of a system in a quantum superposition. A consequence of this dephasing leads to classical or probabilistically additive behavior.
Decoherence can be viewed as the loss of information from a system into the environment (often modeled as a heat bath), since every system is loosely coupled with the energetic state of its surroundings.
That is, components of the wavefunction are decoupled from a coherent system, and acquiring phases from their immediate surroundings.
