Stupid girl just sit there as her Gradp had heart attack

The girl in the movie is stupid and unhelpful. She sees her grandpa having a heart attack and she just stand there watching like a bump on a log. She dumb girl does not yell for help or call 911. She just stand there staring out into space like a space cadet. I have ADHD and stare out in space at times. However, I would have enough intelligence Zandbrains to call 911 when someone was having a heart attack. Just saying.
