To her chagrin, Prudence admits her complicity in all that is wrong about modern Christmas.
Specifically, purchasing Lego.
When Prudence was a tot, Lego was a series of blocks. No people, no trees, no windscreens that only fit boats and no swords. One could make anything one could dream up, there were no limits.
Now, it comes in themed boxes and there is only one possible permutation - the one that matches the photo on the cover.
And Heaven help the grumpy stepmother, who, after painfully stepping on a pile of components left in a doorway, puts the whole lot back in the box in no order!
