Bipolarity

The seminar yesterday was good. There was a good discussion, in fact the audience came up with ideas and comments that I already had and had incorporated in the talk, so I could go on to the next slide and illustrate what they were expressing! HA!

In the evening, we went to the stamp club for a colloqium over the "exhibition rules"(?) in traditional philately and postal stationery. Very interesting and inspiring!
