Some people build up walls around themselves. Others layer on a moat along with the wall. Others have no walls and no filters. A party filled with extreme people like can either be a complete disaster or a fun social psychology experiment. And, becomes it happens naturally you won’t need to go through IRB approval. That’s a bad science joke. Just ignore.
Now while those extremes exist, it does not mean that a comfortable medium point exists. For example, we do need to have boundaries. Where we set those boundaries is up to each of us and where and what is dictated by the norms. However, once you set those boundaries there are two things you should keep in mind. 1) You can change your set boundaries. They can evolve as you evolve. 2) Never feel uncomfortable or embarrassed protecting said boundaries. You set them for a reason.
