The Midnight(ish) Mystery

Last night at about 2:00 a.m. Robert and I both woke up because we heard a loud noise. Of course, we were sound asleep when we heard it so we both weren't really sure what it was that woke us up. After a couple confusing seconds trying to figure out what we heard, we heard it again, "crack!" It sounded like it was coming from our bedroom window. We both jumped out of bed and scurried into the hallway, away from the window. Then we heard it again, a loud, distinctive "crack!" It sounded like something hit the window.

After another minute we heard it again, "crack!" Then I heard a series of "click, click, click, click, click, click." We spent a couple minutes sitting in the hallway wondering what to do. Should we call the police? Should we call the apartment manager? Where are all our phones at? (cell phones and home phone were spread all over the apartment) Should we go into the bedroom and peer out the window? Robert went over and looked out the living room window, which faces the same way as the bedroom window-- into our parking lot. He saw nothing. He decided to call the apartment manager. At this point enough time had passed that I felt like I wasn't going to get hit by any flying objects going through the bedroom window, so I crawled over to the window and looked up at it through the blinds. It was broken.

Poor apartment manager was also now roused in the middle of the night and confused. She told us she was going to look at the security cameras and call us back. It was not a pleasant experience to be rousted from your bed at 2:00 a.m. by some unknown phenomenon, and then have to sit in the hallway doing nothing while all you really wanted to do is go back to bed. A few minutes later the apartment manager called back and said it looked like someone had been in the parking lot trying to get another someone's attention to let them out of the parking lot. Today we learned that it was some dumb high school student, a friend of someone in our building, who had parked in our lot, was leaving, and couldn't get out (we have a gated parking lot, the only way out is with a clicker to open the gate). He also couldn't get back into the apartment building because you need a key to get into the building. Dumb kid not only because he was throwing rocks at the windows (and obviously broke one) but also because he got the wrong apartment! Grrr...
BTW: I never did figure out what the clicks were. Robert claims he didn't hear them, but I heard it right after the "cracks." It sounded like it was coming from under our apartment, where there are some parking stalls. IDK.
