My 6-year-old son has been interrogating me on my Lego knowledge and has found me seriously wanting.
Faced with solving puzzles in the construction toy's latest official annual, I not only failed to save myself from the attack of the skeletons, I also hopelessly befuddled myself in a ruthless fight to the death with some ghastly robotic creature called Fire Lord and his blistering-hot henchmen, cybernuts armed with nitroblast and drilldozer.
How life has moved on. When I last raised children, decades ago, Lego seemed harmless, with most characters taken from everyday suburban life.
I recall friendly truck-drivers and road safety patrol officers - complete with peaked caps and lollypop signs - plus smiling white-coated men delivering milk to your cozy little Lego house, complete with window-boxes and a Volkswagen Beetle in the garage.
Such dwellings have now been replaced with grim-looking barricaded stockades, fortresses to stop the likes of General Nuckel and his skeletons stealing the Golden Weapon of Spinjitzu from some equally sinister-looking ninja warriors.
