When we acquire a new gadget we always keep instructions, and carefully file them away in any number of different places. The places I put them make perfect sense at the time, but not much afterwards. On top of that, when we get rid of a gadget we never think to dispose of the obsolete instructions. One day the house will be full of instructions for things we no longer own, and we will have to move out.
You can't read the f'ing manual unless you can find it, and because I'm not properly organised it's become near impossible to find instructions when I need them. Usually I need them when the clocks go forward or back; or when a battery needs replacing. So when the battery needed replacing on the cycle computer I did what I always do. I had a half-hearted look in several different places to try and find the original instructions. I found all sorts of other interesting stuff, but not what I needed. So I gave up and fiddled around for a while trying to work it out by myself. Just before I got frustrated and destructive, I went and downloaded a copy of the instructions from the web site. Not for the first time, we next had a protracted debate about the best place to buy lithium button cell batteries, until my wife had to go into town. She kindly brought back the ones I needed.
Fitting the battery only took a matter of a minute or two. It took much longer to re-set the clock and enter the right tyre size. I'm sure I must have written down the right setting for the tyres last time, and I filed it with the instructions (how pointless that was). This time I didn't bother. Now the old battery is waiting with all the other stuff that needs to be taken to the recycling place.
It's only changing a battery for goodness sake. How can such a trivial task end up being so complicated?
