I think I would give them a couple of different pieces of advice. One is to look at the top of every letter they send out.
The second is that despite this deeply embarrassing incident, I am defined in some part by activism in political causes. It has been a great experience for me. I believe I have taken out more in life experiences than I have given back. I've made some great friends from all parties, frankly, whom I keep in touch with to this day.
If I may, I should point out that the first person to write to me after this incident was a member of the NDP, who's a dear friend of mine from law school.
I couldn't imagine getting to do what I've done without being politically active.
