Duplo Devastation

What do you get when you bring home from a primary school six boxes of Duplo to sort into the correct container? – a scene on your living room floor that resembles Legoland after an earthquake, even more so when the sets being sorted include police, fire and ambulance; with little guide other than 20 years’ experience, enough progress was made to allocate most pieces correctly, but it helps if in the meantime the cats don’t take up residence in the empty boxes.
