For most of us, not knowing what to do makes us stop for a second in atavistic terror, watching and listening anxiously for the next thing to reveal itself to us. and that pause feels very uncomfortable. Some of us will crouch down, metaphorically or actually, and hope we’re not seen by whatever threat it is. Some of us just leap forward in any direction available just in the hopes it will be the right direction, and even though we run straight into thing this way, it works enough times to be useful. Others react to fear by becoming fearsome, though, and these are the ones we need to be most careful of.
