I've received so many presents - packed in so many cardboard boxes - I need to get rid of now! I put on my boots with high chunky heels and crush them. Some I crush slowly, others get stomped or jumped on. I left the shred paper in some of them - so it gets quite messy after the first boxes! Of course I don't stop until they're all flattened under my sexy boots - that was a lot of fun ;-)
