Our neighbors across the street are a seemingly nice family. I've never had any issue with them or their kids. Their dog is a little noisy and freakish, but that's a dog for you.
The kids, a boy and a girl, are older than my kids. I'd guess that they are probably both in the 12 to 15 range. I'm also not good at guessing ages, but I know neither of them drive yet.
So back to the neighbor kid, the boy, who I'd put at about 12 or 13 years old. He's getting his workout in for the day apparently. He's holding two small hand sized dumb bells above his head and running up and down the street.
I know it's only slightly humorous, and I certainly shouldn't make fun of the kid, even if he looks funny. Mostly it just looks really awkward. It looks like an exercise that someone made up so that he'd look funny as he ran.
