My eldest will be delighted to hear about this. She often teases me about the number of emptied and carefully flattened boxes I have stashed away in hidden corners. Alma and I make models from them, or use them as play houses, or 'dens' in the garden.etc. But I will, reluctantly, admit the supply is slowly and inexorable outstripping the need.
I have an occasional purge on green bin recycling day, which probably makes the bin men think someone else has recently moved in with me.
Now she will be able to tell people her dad is a secret cardboard trafficker, which does sound a bit more interesting than being a mere hoarder.
