Safety Vest!
There's a guy in my neighborhood who I've seen a number of times power walking about,
while over dramaticly swinging his arms(in such a way that it looks like he's competing in a swimming race),
and
he is always wearing a flourescent yellow safety vest
and
talking to himself.
I don't think he has a job that requires him to wear the safety vest, I think he just wears it for kicks.
I see him all the time
and
never once have I thought,
"What a weirdo..."
Instead, I have thought,
"I bet that guy could totally beat me in a running race."
