Since when did we as a society let go of communication instead start ghosting?

Since when did we as a society let go of communication instead start ghosting? Yes, I agree there are times where ghosting is necessary when you have communicated and the other side responding negatively. However when ghosting is done before communication? This is where the real problem starts.

Ghosting is the act of completely cutting off communication with someone suddenly with no explanation. It typically leaves the other person confused, unheard and misunderstood. This is usually done because of fear of responding and what will happen if actual, real and raw communication happens? Basically, it is done because of the fear of confrontation and sometimes, it is just done because they find it inconvenient to talk to the other person. But instead of talking it out, they just ghost. 

This takes out the beauty of our centuries old skills of communication that have been passed on to us through our ancestors. Back in the past, languages didn't exist but they were created by humans to communicate with each other thousands of years ago. Thus, we created diverse languages all over the world to talk to each other, isn't that beautiful? Communication is such a beautiful thing if done in the right manner and at the right time.

When was a time you had been ghosted with no explanation?
