One day at a conference was quite enough for me these days, so I made a good contribution on day 1, then lounged about in my hotel bedroom on day 2. I would have done the same on day 3 had my emeritus professor colleague not turned up at my door to complain about  ‘unprofessional behaviour’.

I argued that (for a biomedical scientist at an information science event) CA had done a fabulous job when she delivered my paper on the second day, and that I trusted her to do the same on day 3. I really was surplus to requirements.
