Leprechaun

Hi. This happened to me a couple years ago when I was about 12 or so. When I look back on it now, it's really not that scary anymore then when I thought it was. Anyways, here's my story. I hope you enjoy it.

I was over at a friend's house one day. I think it was during the summer. My friend and I were just hanging out when I had to go to the bathroom. So I made my way down the hall. As I was about to go upstairs to the bathroom, I saw something standing in front of the stairs. It was a little green leprechaun man. He was about 2 feet tall, he was dressed all in green, and he just kept staring at me. I was pretty freaked out. I couldn't move or say anything. I just stood there watching this thing stare at me. When I finally was able to move, I turned around to call my friend, and when I looked back the Leprechaun had vanished!!

What do you think happened that day?
