Above All: Don't Drink The Water

The water dispenser from the refrigerator makes an odd, creaky noise. I briefly glance at it and continue talking to my parents. Later, during lunch, I take a look at my almost empty cup of water and see little black specks floating in it.
"What is this?!"
My Dad looks up from his meal for a moment. "Do you have black stuff in your water?"
I show him my cup with a worried look on me face, but he just shrugs.
"Don't worry about it; I forgot to tell you that the water filter is broken. It's just trash."
For some small reason, I didn't really feel comforted.

Merry Christmas.
