Discuss the below in detail:
Q: Your neighbor's English bulldog, Cedric, is very friendly, but you wouldn't know it by looking at him. Last Monday, the substitute mail carrier met Cedric as he was approaching the mailbox. Because the mail carrier is afraid of even small dogs, he collapsed from fright at the sight of Cedric approaching, fell to the ground, and broke his left arm. A motorist, who observed this situation while driving by, rammed the neighbor's parked car. The parked car then proceeded down the street through two fences, finally stopping in Mrs. Smith's living room.
a. Is there a case for litigation involving your neighbor?
b. Where does the motorist's liability fit into this picture?
