Late evening walks.
Oh how unexpecting they are! The world around you is so so quite, everyone is peacefully huddled in their homes, shadows move swiftly on window panes, and cars pass by like a whisper in a quite room. The dim street lights force you to zoom in on your thoughts, and the cold breeze reminds you to be thankful for you warm home.
Indeed, it is quite refreshing to venture at night when the world is sleeping, because your mind wanders to such unexpected places.
