Oscillation

Sometimes, everything seems interesting. Sometimes, everything seems mundane.

The oscillation between glory and banality is a defining characteristic of human psychology. The way we think is in many respects defined by highs and lows. Love. Hate. Respect. Repulsion. Loyalty. Betrayal.

Extreme emotional conditions can turn on or off like light switches in the right conditions. One sentence, or even a single word spoken with ample personal implications, can turn bliss into darkness.
