Last night I had told Kerrigan to run in the house and tell Jessica that I needed her car moved for second as I parked the trailer. I saw Kerrigan run back outside and run to Jessica's car and jump in. I initially thought that Kerrigan wanted to drive the car with her. But, Kerrigan had more devilish thought! Then Jessica came rushing out and jumped into her car. From the backseat Kerrigan SCREAMED, Jessica not knowing she was there and was very frightened returned the scream! I could hear Jessica's scream with all of her doors shut from about 50ft!  I wish that I had pictures of that to share, but all I have is the story.
