Something went wrong in my head today. I rose at 8.30am with my alarm, dressed and drove to town to pick up my mail. Arriving, I discovered that the post office was shut - and everything else too. I was confused, so I checked my watch. It said 9am. I then wandered over to the post office door and checked their hours. The sign told me that they open from 8.30am. "Could it be that they are late today?", I wondered, "But where are all of the people waiting outside?" Still confused, I checked my watch again. One time recently it showed the wrong time, so maybe it had done it again and I was here are some unearthly hour of the morning such as 6am, thinking that it was really 9am. I grabbed my mobile phone and checked the time on that. It agreed with my watch. That made things really strange, because it received the time from the network and was never wrong. Then slowly it dawned on me. This was not Monday at all. It was Sunday. My day to sleep in, and here I am, still half-asleep, the day after our big drive from Buenos Aires, totally confused about which day it was. Sunday had become Monday... just for a moment. Doh!
