You scared the crap outta me!!! I was very calmly watching the video, with audio, for a while. I eventually closed it and went on my merry way. A while later I heard voices. No big deal, I thought it was the giant voice (I'll explain in a minute) so I went to the door to hear it better. It went away. I went online because they post the giant voice messages on facebook. There were no giant voice messages. I was getting worried. The giant voice never speaks this late unless there's something wrong. As I'm looking at facebook, the voices suddenly sound like they're right next to me
I closed facebook and that's when I saw the tiny audio window still up.
At this point I'm assuming that's what it was. I closed it so fast I didn't even check to see if that's where the voices were coming from. I haven't heard them since, so I'm pretty sure my near heart-attack is your fault.
