Abby was walking down the street and now she felt pretty good. The street was empty, no one was walking around, the surface was flat. At such a moment, no one would even notice anything unusual. But that was to change in a moment, because Abby was to come out of a side alley and join a much busier classroom. In addition, several steps led to it. When she saw them, she even felt unhappy for a moment, expecting the suffering. And the first step up the stairs really caused some form of suffering, which in a sense was very pleasant.
