有种希望叫正在发送有种绝望叫发送失败
[yŏu zhŏng xī wàng jiào zhèng zài fā sòng yŏu zhŏng jué wàng jiào fā sòng shī bài]
It's a metaphor drawn from the modern digital communication era. There is hope when you're sending a message but also despair when it fails. In this context, it means that we sometimes have anticipation but often end up disappointed.
