person A: Today_comma_ I ran over some roadkill on my way home from work. It was rather disgusting.
person B: Oh no! What was it?
person A: It was a dead possum. It was in one piece before I ran it over...but I didn't see anything behind me when I passed it. My tires must've grinded that poor little guy into smithereens. 
person B: Yikes! I hope you didn't have any car damage.
