Was heading into work later than usual this morning because I had to wait around for the electrician to fix the bathroom light switch (which was making disconcerting zapping noises). When the train got to Flinders Street I noticed a young man in the next carriage wearing a surgical face mask. I surmised that he must be wearing the mask to avoid catching swine flu. This was the first time I had seen anyone wearing a face mask outside of a hospital or a dental clinic and he looked a bit strange doing so. I guess he must have felt quite self conscious about it. A few stops later, the young man had taken off the mask.
