Mea culpa.
I would like to point out that I am 11 1/2 stone and Iain is 17 stone and goes to the gym most mornings.
The pub was only open for 2 hours on Christmas day and the first 6 Guinness went down just fine. He then bought a round whilst I was in the pisser - with the large Port&Brandy. Obviously I had to return the round and as we were close to finishing that, I went for another piss to avoid an urgent need on the 2 mile walk back home.
Came out from the pisser and he'd sneaked another round in, as he's a regular there.
We walked (in my case staggered) back to town, where he carried on to his place and I went to mine, up my long hill. Halfway up the hill, the urge for another piss became all-consuming. Once the seal was broken etc...
Stupidly tried to run up 2 flights of stairs, left foot missed a step and slammed into them. Didn't really feel a thing at the time, but had a long piss, a 4 hour snooze and only woke due to hurty ribs. And bloodied fingers as I'd obviously scraped them somehow.
So it's Iain's fault 😕
