This I (still) believe:
Fire is not necessarily your friend. Neither are dogs. Things with lit fuses should not be held onto. Beware the savage croquet ball. If it is -30 out, put on a coat before you leave the house. Just because the snow keeps you from seeing other objects the objects do not cease to exist. Clotheslines are the enemy of the bicyclist. If you don't remember how you got on the ground or where the blood came from, don't get up right away. Gym teachers think it's funny to commit assault with a baseball so don't day-dream during PE even if they have you so far in the outfield there are DEW line posts on either side of you. All guns are loaded. So are many bows. Trebuchets are for outside use only...
