I thought that this year for once I had escaped the routine festive dose of bad luck, but no - on the 27th it struck.
SWMBO was getting very wound up about not being able to find the car keys so I pitched in to search the house. They were irretrievably lost. Logical questions such as "where was the last place you remember seeing them" elicited the usual sardonic response in a raised voice, so establishing a timeline was impossible. Having nearly dismantled the house and reached a dead end, the emergency spare keys were brought into use. The consequences of losing these did not need pointing out.
On 28th, there was a nasty surprise when the toilet blocked. The bowl filled up and refused to empty. Both types of effluent were in abundance in the mixture, and both of us blamed the other and Christmas food excess for the log jam. About fifteen minutes of prodding, rodding and plungering finally freed the mess and many flushes later the bowl was running clean. SWMBO then tipped some concentrated bleach into the bowl and after a clean up, I retired for a drink.
The following day, when just about to syphon the python, I saw something in the bottom of the toilet bowl trap. Reaching in, I found the car keys, electronic fob and all.
The fob was dismantled and all components thoroughly cleaned. The electronic bit was dried as well as possible with kitchen towel, the battery removed, and the fob put in a sealed plastic bag with rice (Basmati) in it overnight in the airing cupboard. On re-assembly it worked perfectly. You have to applaud VW. That fob certainly performed beyond the call of duty.
SWMBO refuses to touch the normal keys now. Bad form really, as we have mutually established that it was her that dropped them in it. Smirk.
