I realised I needed to go to the loo. I politely excused myself and made my way to the bathroom. Needless to say, I did an unfurtunately large turd that refused to flush away, the brush wouldn't even help. I had to scuttled downstairs and get my girlfriend to fetch the Marigolds (all without the parents noticing...even though in the same room at this point!). This got the interest of her little brother going, so it ended up with all 3 of us in the bathroom, me trying to push the stuborn log around the S-bend, just as I reached too far and the rubber glove dipped below the "water" level, thus filling up, the mother banged on the door to ask what we were doing..."Nothing!" we all replied in unison.
I seem to remember spending the rest of the tea-drinking awkward evening chatting with the folks thinking only of the tainted rubber glove hidden in my pocket.
