Personally i do this alot. When i watch game of thrones i dub that shyt an make jokes an what not. When im surfin the web i laugh an comment on threads/videos. I dont think its weird i couldnt imagine sittin there quiet for hours, i dont know why i feel compelled to do it but i just like wildin out sayin stupid shyt, sometimes when im thinking about something i talk quietly to gather my thoughts. I feel like most ppl think this is weird but i dont really care, just askin. I saw this girl talkin to herself while walkin around campus, thats when i realized how weird it looks.
