Going back to the game, I mean the difference between a Resting target, an Agitated target and an Alerted target.

A Resting target would be anyone just going about their everyday life, with no concerns in the world. They wouldn't notice a Stealth Expert pickpocketing them, or picking a lock nearby or something similarly sneaky, but may become Alerted if an unskilled person tried to do the same thing.

An Agitated person would be a patrolling guard, or someone in a more attentive state who'd be looking out for trouble. They wouldn't notice a Stealth Master performing a dastardly act, but would be Alerted by an Expert or unskilled person trying to.

An Alerted person would be a guard chasing an intruder or engaged in combat. There's no chance even a Stealth Master would be able to pull off a sneaky feat while someone was actively watching them and even possibly shooting at them, unless someone else could somehow distract the Alerted person away (time to break out the cocktail dress, or lack thereof. :lol)
