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 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!
