... what went into a concrete sidewalk or some such? By 12 yo, I had never seen anyone mix concrete. The man across the street was fixing-up his culvert with a bank of concrete: a few reinforcing bars, gravel, sand, cement and H2O. To finish-off, he used the trowel he pushed the gravel sticking up out of the cement down INTO the cement, hiding it from view, then smoothing-over it all. I asked, "Does all concrete have gravel pushed-down into it?", and the man said, "Get the fuck out 'a here!", or something educational. So, when did YOU find out about concrete or some otherwise obvious thing? littlexs: age 5 yo |
