I'm so used to leading a double life - by day, mild-mannered secretary/typist/bookseller/whatever, by night EVIL SLASH FAN - that I'm pretty sure I've managed to maintain the facade even when I've got so drunk that I've ended up at quite the wrong end of the Tube line, which wasn't the right Tube line in the first place ...

That, or everyone else was even drunker and didn't notice.
