A joke gone SERIOUSLY wrong!

I work at a wonderful job where I have lots of people with whom I can joke. There is a security guard that I often banter with, who sits on the main level of my building. I leave every day to do a "run", and on this particular day I was driving back from my "run" and drove up the ramp and my friendly little security friend was running down the ramp. She was running down the ramp to try and catch some hoodlums who were skateboarding in the underground parking garage. As I was driving up the ramp I nearly hit her but being as stealthy as she is, she dodged my car. But being the silly girl I am, I wrote (yes, wrote with a pen and paper) a note and put it on her desk. Oh, I forgot to add that sometimes other people sit at that desk when she is doing crazy things like running after skateboarders. Ok, back the story. So the note is at her desk and someone else picks up the note and reads it. "I could have killed you! You young whippersnapper! :)" is what the note says. I even put my signature smiley face on the note to make sure she knew it was a joke. But like I said, she did not see it first. Another woman, who is an assistant of a government official, saw it and freaked out. Now we have the police looking at this note, plus a whole slew of other people including the official himself!! I did not know this until today. So apparently this silly little note got everyone excited. Of course, after I told everyone the context in which the note was written everyone calmed down. I learned my lesson not to write a note with the word "kill" on it.

P.S. I did get to those papers from my last post, finished. I can hear the sighs of relief! Thank you! Man, this quarter is killing me! (oh crap, used the word kill again)
