Because we grew up surrounded by big dramatic story arcs in books and movies, we think our lives are supposed to be filled with huge ups and downs! So people pretend there is drama where there is none.
That's why people invent fights. That's why we're drawn to sports. That's why we act like everything that happens to us is such a big deal.
We're trying to make our life into a fairy tale.
