Yes, this is my diary entry for August 25. THE FUTURE. Yes, it's a form of time-travel. I predict I will be doing my show in Napier on August 25. I've just returned from the future, and I can report, the GIG GOES REALLY WELL. So book tickets. You're going to anyway. (Or will you?) OK, maybe don't think too much about the time-travel aspect.
Just book tickets. The Future-You will thank Now-You for it.
