How did that Glitter get in my Nose?

I was cleaning the house on Saturday, and as I scrubbed the bathroom sink I looked up at my reflection. I noticed a little light reflecting from my nostril and thought to myself, "I can't feel my nose running but it must be." Then I took a closer look and determined that there was glitter in my nose. How did glitter get in my house? And once it arrived, how did it get in my nose? Was it in the process of entering my body or exiting?
