Find a thought:
I was feeling quite stressed, and I was in possession of graph paper. So I started writing down letters, randomly, but in order, in each box. But it quickly became boring and I was having trouble randomly choosing letters. So then I started writing out the alphabet in order, at "random" positions in the grid. This was fun, and I wrote the alphabet down forwards and backwards several times.
However, this also became boring. Then I realised I could write down ideas that were running around in my head; things that I didn't really want to think about, but was thinking about. It was actually quite relaxing to be able to express these thoughts on paper, but not in a way that anyone else could recognise.
So now this grid exists, containing a whole bunch of letters in no particular order, and then a whole bunch that meant something to me, but are now completely unrecoverable.
