Communication is incredibly important in our lives and quite frankly, humans depend on it for adequate interaction. There are so many ways to communicate in today's day and age and unfortunately, due to this, it can result in negative and misunderstood interactions. I remember a time when I was little when I used to go to this park every day and there would be these set of identical twins there as well. They had some sort of secret language amongst themselves but this was misinterpreted by another group of young girls who told their mothers, who eventually called the police. This turned into a large argument between the group and just goes to show how communication can make and break relationships and interactions. Humans desire to feel understood and accompanied and when they don't, arguments start to arise, especially when that same little communication spreads.
Hope this helps :))
