Small things in life that gravel your ass

[Rain Man]

I'm sitting in a mall, and the guy opposite me is moving his head as he reads, so I can tell where he's at on the page and on each line in the page. I find that more curious than annoying. What's mildly annoying is when people move their lips as they read, but I can generally look away if I see it so it's not a huge issue.

This is unlike people who don't eat peanuts properly, which compels me to stare as I try to understand their strange ways.
