My dad put a cup of water in my car during tofu deliveries to a hill resort. He said it was to ensure the tofu didn’t get damaged in transit. But he was secretly developing my downhill racing technique. Apparently if I didn’t spill the water, it meant that my cornering technique was ‘smooth’.

Also the kiddie version of ‘wax on wax off’ is ‘hang your jacket on the hook, take your jacket off the hook’.
