Phatic communion, like most aspects of communication we will learn about, is culturally relative as well. While most cultures engage in phatic communion, the topics of and occasions for phatic communion vary.
I first came across this topic when talking to a friend visiting from another country. She wanted to know why in America we say hello to everyone and make small talk. My first impulse was to tell her it's just what you're supposed to do, and not to be rude. While the concept of different countries having different norms seems obvious in the moment, I was a little surprised she didn't do the same at home. Phatic communion was something so simple yet such a regular practice for me it feels like second nature. So, I find it very interesting to learn about what is considered phatic communion in other countries.
