Virus To A Cell

Peculiar creatures, order providers
Eyes everywhere gaze with weary intent
Familiar faces, never outsiders
It's best to make haste, time need be well spent
Misunderstanding brings forth needless change
Destroy what is foreign, eradicate
Search the perimeter, all that's in range
A slight discrepancy closes the gate
Never leaving room for variety
Quarantined but internally tattered
That's life in a close knit society
Never succumbing, though bruised and battered
Better stray away from this simple test
Find ones rightful host, blend in with the rest!
