Picking up the paper - you see that it is a note from Betty the Badger to Tommy Tomkins:

Tommy dearest,

Just popping outside to collect some grubs for tea. I thought I'd make grub pie tonight. Hope I don't get badger-napped along the way!

Your badger, Betty

If only she hadn't gone to collect grubs then none of this would have happened. This makes you angry at all that is bad in the world. There is only one door at the other end and you fling it open in your rage.
