I know what you did.. the night on halloween

It was a dark, halloween night. Boys and girls were getting ready to trick or treat; A little boy name elvis was dressed up as elvis (how ironic); Him and his sister were about to start off on their two hour candy journey when Elvis spotted something in their mailbox. It read "I know what you did.. on the night of Halloween". Elvis and his sister thought it was a joke so they thought nothing of it. When Elvis and his sister got halfway through their neighborhood, they saw another letter. This time, Elvis's sister read it; "I know what your doing... tonight". His sister turned around sharply making sure no one was watching them. They see a person watching them from across the street. They start sprinting back to their house and they turn around and the creepy guy in the mask was no where to be found. We begin to slow down and finally come to walk but still looking behind us. We turn back around and the guy with a mask is right there! Elvis starts screaming. The guy in the mask puts his hand over Elvis's mouth suffucating him. Elvis's sister kicks the creepy guy in the stomach and he falls to the ground. His sister lifts his mask up and realized it was their dad.Elvis's sister had kicked their father so hard, that he died. HAPPPPPPPPPYYYYYYYYYYYYYY HALLLLLLOOOOOOWWWWWEEEEEENNNNNNN
