Melissa the Muppet
I was ready to head off to the tip and standing by the bin bags when Melissa walked past. To save me going upstairs I asked her to go and get the bin from her bedroom, and called Cammy to ask him to get the one from the bathroom.
Cameron duly turned up with a full bin which he put in the black bag, but Melissa turned up with an empty bin. What a Muppet I thought, why bring it down if it was empty. So off to the tip I went.
Later that day when putting Melissa to bed I heard Sara say, "Oh Melissa!!". When I went up to investigate it turns out Melissa's muppetry was greater then we thought. As I had asked her to bring the bin down, it seems she took me at my word, and emptied the rubbish on the floor in her room, before bringing it down. Muppet.
