Hiccups are unlucky because when you have them you are believed to be owned by the devil. 

Hannah: Hello. This is Hannah. I am interviewing Mrs. Nicole M. West. She is my friend's aunt's cousin's daughter. 

Nicole:  I do not remember much.  I was just a baby.

Hannah:  Are you sure?

Nicole:  Yes, I will tell you what I remember.

Hannah:  Go ahead.

Nicole:  Okay.  Well, I was sitting in my highchair, getting fed, some applesauce, I believe.  It was noon, and I was getting all the attention, and my older sister, Lila, had the hiccups.  Now, since we weren't superstitious, it was nothing to worry about.  Except it was kind of backfiring.  Each time she hiccuped, I jumped 10 feet.  I started crying.  Lila started screaming, "I HATE HICCUPS!!"  Mom yelled back at her.  The floor popped open and I stopped crying.  Lila stopped screaming and so did Mom.  There was smoke and flames and I thought I would die.
 Lila disappeared that night.  Forever. 

Hannah:  What a sad story.  Thank you Nikki.  By the way, how old are you now?  How many years ago did it happen, and how old was Lila?

Nicole:  I am 38.  It happened 37 1/2 years ago.  Lila was 8.

Hannah:  Thank you. 

Nicole:  I forgot to say some remedies for hiccups.  Some are peanut butter on a spoon, getting scared, and drinking from the opposite side of the glass.
