The medieval battlefield of your immune system! King Macrophage and his squire Dendritic Cell are patrolling the central nervous system when they spot the bacterial invader Streptococcus pneumoniae lurking where it doesn't belong.

Classic bacterial entitlement—breaking into your cerebrospinal fluid then acting offended when the immune cells show up. It's like catching a burglar in your kitchen who then complains you're interrupting their dinner.
