jj, why do you think most roads and pavements, (here, at least) are covered with black tarmac?
Because it's mostly made from by-products of the oil industry, readily available stone chippings, often recycled, and costs bugger all to produce, that's why.
Cement based flags look pretty good, as do those made from stone. Traditional cobbles are nice, too; all are of the white persuasion. Want me to give you a price to create a driveway using them?
Don't even ask unless you're very, very wealthy.
Shit happens. The older you get, the more often shit happens. So you have to try not to give a shit even when you do. Because, if you give too many shits, you've created your own shit creek and there's no way out other than swimming through the shit. Oh, and fuck.
