Of course, if my dad ever sees that I made a comment like that about him on the internet, it might be hazardous to my health...I would cease to be in the pink.
But what about if I'm feeling envious? We say I'm green with envy! Does that make any sense to you? They say that jealousy is the green-eyed monster, but nothing about me really turns green when I get jealous.
Then when I'm sad, I'm blue...like maybe I was singing the blues or something? Or watching Blue's Clues? Last time I was feeling sad I looked in the mirror, and my face wasn't any more blue than usual...maybe even a little more pale. And if I'd been crying, well then, I'm sure my face would be all splotchy with red, not blue!
