Cathy took Sam to the local greetings card shop to buy an advent calendar. Underwhelmed by the lack of choice they picked one and took it to the counter, cold hard cash in hand. Suddenly, as is wont to happen with little boys, Sam decided that he wanted a wee wee: right now! Cathy smiled that kind of parent smile and asked if he could use their toilet. "Sorry, we're not insured for that." Was the reply. With no money or advent calendars changing hands, Cathy marched Sam out of the shop to have a wee against their wall. I'm often caught short on my way home from the pub on a Friday night after several pints of best real ale and could, with a short detour, pass the local greetings card shop, mwhahahahahah!
