In case of emergency, break glass! On the face of it, that seems like some pretty odd advice for dealing with an emergency. Now you’ve got two emergencies, the regular one and the broken glass. However, it feels good to break glass when agitated. That lightens up the atmosphere considerably, allowing you to focus calmly on the emergency at hand. The sole exception to this rule is when the emergency is broken glass. In that event, don’t break any more glass. Always read these situations carefully before proceeding to avoid making a bad situation worse.
