We all know how to communicate with each other, right? We do it all the time. We talk to each other, phone, email, text, PM. Back in the old days, we wrote each other letters. All of these make use of spoken or written language to get our points across. But not all communication is spoken or written, and not everyone communicates the same way.
For example, we’re probably all aware of body language and how to make use of that. If you’re speaking to someone across a table, and they lean in, that probably means they’re interested in what you’re saying.
