You know your houseguest is English when...
* songs by trendy young bands with foo-foo haircuts keep showing up in your downloads file.
* your local liquor store has sold out of merlot.
* and prosecco.
* and tequila.
* a mini-keg of Grolsch has appeared in your fridge.
* your liver has ceased functioning.
* your downstairs neighbor's back garden looks like an ashtray.
* your downstairs neighbor isn't speaking to you anymore.
* a mini-keg of Grolsch has disappeared from your fridge.
* a week after they've left, you go to sample your "secret stash" of dark rum and find that IT'S GONE.
