We all know what moods and emotions are but it takes a great poet to describe them without despoiling those mighty, awesome, awful “things” we feel inside of their very nature. Still an image can convey emotions way more easily than dry words… don’t believe it? See for yourself here.
Feel like objecting that some of these images should belong in “humor & fun”? Of course: humor is an emotion too, probably the most powerful one after love!
