We recently saw a commercial for Shark Week and had to laugh, remembering this ...
When our granddaughter was around 4 years old, we were watching TV and a trailer for the original "Jaws" movie came on. It came to the part (about 1:50 on the video clip) where the girl is swimming alone at night and the shark grabs her and drags her around while she screams bloody murder.
I froze and looked at the kid, thinking, "Oh no, this is going to scare the daylights out of her." She was intently watching the screen and all of a sudden the girl goes under for the last time and it's dead quiet.
I was holding my breath, wondering if she'd start crying or what she'd say. She looked at me and said in a very nonchalant manner, "Well, that didn't take long." It didn't even faze her!
