Originally I intended to write: You know you're very busy when it gets to 7.15 pm and you realise you've forgotten to eat at all during the day. (Actually almost a repeat of a post from some time ago, with only a slight change of time.)
Then I realised that I was wrong, having forgotten a brief highlight of the day. So, in a weak attempt to maintain whatever integrity in terms of factual accuracy this Far Place sustains, here's today's reconsidered entry:
You know you've been very, very busy when it gets to 7.15 pm and you think you've eaten nothing and suddenly remember the samosa you ate at 2.05 pm and realise you've (almost) completely forgotten a moment of pure joy.
