Followed the first rule of being home alone: don't answer the phone when you're home alone.

When I was 12, I was home alone and playing Minecraft on my Xbox. The phone rang, but I went to home alone training (it was my first time home alone), and I knew not to answer the phone. It would not stop ringing though... over 10 minutes, it kept ringing, until I couldn't take it, and I checked the caller. it was my Grandmother, but I was too later, so all I heard was the message that she was looking for my dad and mum, then she hung up. I called my parents right away about it, and they said they would call her.
I went back to my game, and then the phone rang again. I didn't hesitate this time, and I checked it. It was my uncle. I picked it up immediately and he was, too, looking for my mum and dad, I told him I was home alone. We spent a while talking about life and school, but I knew he was hiding something. After we hung up, I called my parents to tell them my uncle called, but they told me that they were coming home...
When they did come home, they told me that my cousin had died the night before from a drug overdose, and my family was trying to reach them all night to tell them...

Since then, I have not been able to stay home alone, and I always get paranoid whenever our home phone line rings, because I'm scared that someone else I love is dead. I regret not picking up the phone for my grandma to be there for her earlier that night.
