"An unwanted souvenir"

You can expect festivals to leave you with a hangover like death and a bank balance well in the red. What you perhaps don't expect, though, is that you might end up suffering from a dose of trenchfoot. That said, if you're a Glastonbury regular then it might not come as that much of a surprise. Quite how I avoided it I'm not sure, given that for the entire Friday I was walking around sockless in boots filled with sloppy mud. Wisdom and rationality were in short supply during the deluge, I can tell you.
