I stayed overnight at my grandparents' house fairly often when I was a kid. Usually all of the grandkids would go and have a good time annoying the shit out of my them with pranks while our parents enjoyed a night off. One time, my grandma came down with "the flu" and was sick all night and all morning. The kids scrambled to wait on her and leave her little presents to make her feel better.

Except for me.

I spent the night in terror hearing her get sick, alarm bells ringing in my head. I couldn't move. I couldn't even go near her. I got yelled at a bunch by the other kids for "being weird."

In the morning, when my parents showed up, I told them, crying, how scared I was and that something was wrong. They were basically just annoyed and said it's just a stomach flu, chill out. We went home.

Spoiler alert: It wasn't a stomach flu. Grandma'd had a heart attack sometime during the evening.

A few hours later my grandpa was frantically calling us because she wouldn't wake up.

Everyone was upset with themselves for not realizing. I was upset because I did realize, on some level, that she was dying, but didn't really understand it consciously. I wish I had made a bigger stink about it.
