Enforced cheeriness

I decided to nip up to the post before it started raining again. Nip! The traffic was so heavy/fast/blocking the road that what should be a two minute walk turned into a life-risking expedition. Every single person I met was grumpy. Once in the shop a voice in my head said, ‘You must buy the Christmas Radio Times! You must buy the Christmas Radio Times!’ Resistance was useless: look what I came home with. Curses.
