Well it gets worse. The taxi didn't show up, queue a very long walk through very dark country lanes with water filled ditches at either side. Thankfully dad was prevented from toppling head first into one, but about 10 minutes from home he'd had enough and laid on the ground unable to move. Clumping his head on the way down. When he was eventually dragged home he had a great big shiner and a grazed head. 12 hours later he was still lying on the sofa sleeping and making the odd bit of conversation when he woke up. Allegedly he wasn't concussed, but I did advise going to the doctor's today if he was still in that state! I don't think I have EVER been that drunk. Go dad!
