I weigh in around 220 lb. My wife weighs about 120 lbs. She makes more noise crossing a room then I do. It's not a matter of shoes, I make less noise shod then she does barefoot most the time. She (until fairly recently at least) is just totally unaware of how loud she is as she goes about her daily routine. It's unfathomable to me how anyone can be unaware of how loudly they walk. I don't know if it's growing up in apartments, being sneaky, or just paranoia that makes me aware of how much noise I make. Most people seem generally unaware of some aspect of their sound profile. At it's most garish this unawareness is nothing but astounding and profane. This unawareness is a quality I loath in people. I feel something like relief to reading "The Quiet Ones" I am not alone in my preoccupation. I think there are many other things that I find offensive which go unmentioned in our society, things like TV's in public social spaces. I like that someone has named one of the accepted evils of our time.
