Definition of Exhaustion: Taking two children to Save-A-Lot to do a big shop (we're talking a full cart) and having your daughter go from singing at the top of her lungs to crying and sobbing because Momma decides not to get the beef bouillon. After explaining to your daughter that she wouldn't like it anyway, the daughter begins to cry over something else which leads to crying over something else which leads to your son crying and screaming high pitch.
