They are very picky and choose where and when they go ALL OUT.
Some never daee go ALL OUT for fear once they are out there no one will notice their absence. If they really invisible they'd rather not know it! So they stay where they are and just bobblehead. Agreeing with your surrounders may not get you noticed but it won't get you bounced shunned attacked either. Safety rules.
Are you picky? If so how do you choose when to hissy fit back and when to just let it slide let is ride let is glide over you?
