Sick Boy, you need to fake your own exit (bang door, flush, run taps, bang main door) then sneak back into the cubicle and then greet their effort with an enormous cheer.
Indulge my Reader’s Digest-style tale. I’ve been having a longstanding argument with someone in which I have maintained that they are a div for never having heard of a certain famous pianist. This person informed me yesterday that neither of her flatmates had heard of this pianist either, so I said, ‘email X and ask her, if she hasn’t heard of him I take it all back about you being a div, he is evidently not as famous as I thought he was’. Today I received a triumphant email that said ‘well I’ve asked X, and she’d never heard of The Lonliest Monk either’.
Polite chortles on a postcard please.
