Guess I'm now officially 'not a good housekeeper', lol.
I want to point out a misconception on the OP's part, in the text he chose to highlight. The 'them' referred to are the "mostly 14-18 year olds" who responded to the mayor's request.
Joe: you've raised boys - did not they see a snowstorm as a great opportunity to make a few extra bucks with a shovel? I know my girls did, and even though it's a looooong time since I was a teenager, so did I. So why assume the teens weren't already shoveling? I'd bet they were, but they mayor's offer provided the one thing many of them desperately want: certified proof of prior employment, as evidenced by an actual pay stub. When you can't get a job because you've got no experience at a job, that's priceless!
I applaud the mayor for dealing with a difficult situation creatively, and for helping to teach people what 'community' means. Somehow, in all the civics classes, I don't recall the concept being presented.....
