Oh boy do I get how it feels like to have people around listening to you when you're recording. Wherever I go, there's ALWAYS someone minding my business. If people were flies, I'd be a stinkin pile of poop.
The way I'm going to deal with my situation, is to get one or two friends as my camera guys, and I'll start recording in public locations. Hiding in shame comes across very strongly on camera. And that's painfully obvious in your video. Can't you get a girlfriend to be with you, so you can be as hysterical as you want to the camera, but you'll have someone there to take all the blame for the noise.
