Grandfather Clock

So today was a really stormy and gloomy day. Normally I love these kinds of days because I can just relax and watch some good movies or TV. Well I was sitting on the floor this afternoon with my one year old niece, my mom, and my older brother when we hear the really old grandfather clock in our hallway go off. My niece jumped and ran towards me. The scary part is, it hasn't gone off in over two years. It was also set to go off exactly on the hour which is extremely hard to do on our clock.. The only way that the clock will go off is if someone winds it up. The only one in our family who knows how to wind it up is my dad, who is out of town for the week. When I asked my mom about it she just shrugged and said that it has been going off all day. I have no idea how this is happening, but now I'm laying in bed and I'm dreading hearing that clock toll at 11 and then 12 and then 1 etc. Everytime it rings I get chills simply from the fact that no one knows why it is suddenly working. This is a legit true story. I'm not lying. I'm scared fucking shitless right now.
