Mood changes are strange. They’re brought on by strange things. They are experienced by strange people. And thought of by profound people. Which means that I am profound, as I appear to be thinking of them.
By the way, mood changes also make people tired. At least they make me tired. If I were to go through a mood change, that would make me tired. BUT, if I were tired, it would not necessarily mean that I had gone through a mood change.
Even if I did.
