Crazy Visitor

Sometime around midnight last night somebody was banging on my front window and yelling outside of the house.  I was studying for the Praxis exam at the time.  It was a pretty intense situation that hit me suddenly. I didn't know what the was being yelled. I approached the front door and looked through the window at the top of the door.  There was a young man outside, probably late teens or early 20's.  He was tall with long blond hair. I didn't know who he was and couldn't figure out what he was saying.  All I know is that I was a little startled. I yelled through the door that he needed to take of or I would be calling the police.  He said something and then said he was leaving and he walked off. The dogs in the houses behind me started barking so I figured he was walking around over there  I did go check the backyard and looked around the perimeter of the house.  All was clear.  It was a tough situation, pretty intense  I did call it in to the police. Don't know what became of it but I stood guard for a while to make sure there was nothing to worry about.  All was fine.
