Deep Listening..

I decided to do my listening exercise while I was waiting in Ovalwood across from the auditorium.
It was about 9:30pm, so most people were already on their way home. At first all I heard was the fan systems going on and off, and then as I kept listening I could hear faint knocking sounds, maybe coming from the fans, I thought I kept hearing people talking far away, but I couldn't tell. I also thought I hear someone walk in the far right door and then turn around and walk out, I even thought I saw their leg. (I think I was just freaking myself out). I heard the ladies who work in the cafe putting things away, I could hear the wind swirling around the building, and through the trees. And then I did hear footsteps and keys jingling, it was security checking all the doors. My listening experience was really creepy, especially because I was alone, at night, and it was storming.
