Once more, with feeling

I'm awake now. I woke up to see my bedroom window open, the locks utterly fucking smashed. three things are bothering me. One, I live on the third story. Two, my locks are on the inside of the window, and three, there are no signs of an entry, to do this to my locks. Nothing's gone, but I don't feel too good. I'm getting new locks. Adding to that, I'm also buying bars for my window, as after close inspection, all other windows in the house are fine. Whoever did this is fucking with me, and I'm done playing little kiddie games with that salesman. next time I see him, I'm dropping him in a fucking hole.
