I’m an old guy who reads a lot and writes about stuff on occasion.
On a more long-winded personal note: My Arizona home has rocks in the yard instead of lawn and I don’t like rocks on my sidewalk. Typical crabby old guy stuff, but that said, I think kids and dogs should have fun which means lots of rocks find their way onto my sidewalk. I will not hassle the kids or dogs about it, because that would wreck their fun which I enjoy seeing all around our home, so I sweep a lot and also enjoy the meditational value of that activity – not to mention the free Vitamin D.
