You were a survivor of a sudden parasitic infection that made a regular person into a creepy, lengthy smiling freak... Most infected seemed hostile and merciless when fully infected...

You were walking in a building, collecting food that was left over, a can rolls over to a corner of the abandoned store, you go to pick it up and look up to see an infected... You immediately jump back, dropping your weapon and landing on your back...

The infected tilts its head and stares at you... It didn't attack you... It's plastered smile and widen eyes were creepy...
