Dramatic people

When I was in high school, I was surrrounded by teenagers who allowed drama to consume their conversations. I recall thinking to myself, "as soon as I am in college this will cease". Needless to say when I began attending college, dramatic people still resided. I cannot seem to understand how people have such difficulty with getting along with other people. I understand that nobody is the same and personalities vary, however I cannot figure out why people insist on judging others negatively. I suppose there are things in this world that we will not understand, until then, keep wondering.
