I mentioned that I've been watching Twitter. We had a first here today, and I want to thank Professor Macfarlane. For the first time ever I've been able to tweet with a witness while we've been talking here at the table.
Another Twitter commentator, Chris Conway in Invermere, B.C., has asked me to ask you, Professor Macfarlane, why you are biting your tongue and what it is you want to say.
