What does it take to turn one perfectly packaged letter into a papier-mache mush?

1. One perfectly packaged envelope, posted to the wrong address
2. One hand-delivered attempt to rectify the problem
3. One idiot (me) leaving it in a friend’s house in London by accident
4. One attempt by said friend to forward the mail on a rainy day
5. One postal strike
6. Four weeks later

That is how you turn a perfectly packaged letter into a papier-mache mush.

I might have just as well just had it posted to the correct address in the first place, put it in a blender with the rest of the ingredients for a banana smoothie, hit ‘Turbo’ then pour after a month.

It might not have been so bad if the contents hadn't been electronic.
