is it me or was there a really high pitched noise at the very end of the video. I'm going to assume that was intentional if it was one of those misquito alarm things (which I have never heard of before are they a thing in the states?)  if so I can see how teenagers are annoyed by them it was ab 5 seconds long and i already felt a headache coming on. also I'm twenty should I celebrate or wait another 5 years to celebrate on being able to hear it. (is going to be very embarassed if there was no noise and my ears were playing tricks on me
