It looks witchy but it's a physics thing which I don't understand but like looking at. A slow day after yesterday's busyness. Met a friend at night for dinner. We shared our cultural experiences which were very different but interesting to hear about. I explained about advent calendars which she had seen but didn't know what to do with. I didn't realise before I gave it to her but ( I gave her a small card version which she was delighted with) she hadn't had one before.
