Another annoyance...

I know the list of things that bug me seem to grow greater daily, but i'm honestly not a moaning old man. Here's my latest thing, Flip flops or more specifically any footwear that makes that annoying noise when the footwear owner walks. On the scale of things it's pretty low down my list and I will admit being very fussy about footwear but come one doesn't the 'flip flop flip flop...' really make you grate your teeth?
