As the station wagon pulled back onto the highway, the sun was slowly sinking below the horizon like a leaky boat. Well, except for that fact that boats are not generally round, orange and on fire. Hmm. Come to think of it, in no way whatsoever did the sun, in this instance, resemble a leaky boat. My apologies. That was a dreadful attempt at simile. Please allow me to try again. As the station wagon pulled back onto the highway, the sun was slowly sinking below the horizon like a self-luminous, gaseous sphere comprised mainly of of hydrogen and helium.
