It's funny, last night I went out and got completely rat arsed. No real reason but I just felt like it and I haven't been out since New Years. Only now I realised it was Oz day.
Similar thing a few years ago. I was on a yacht in the Galapagos and was telling the Captain how I felt like a couple of beers and it must be a day of celebration somewhere in the world so I looked in a book to see if there was something and low and behold it was Oz day. I put an Aussie flag up the left spreader and the Captain (who is seppo) told the owner who was on at the time that it was Australia day and we are having a few beers. "No worries" came the reply. Good boss that!
