Old co-workers week: A few nights ago I spoke with my friend Nathan. He and I worked together a few years ago in DC at Americans United. We've been very good friends ever since, and in fact I've become close with his whole family. His replacement at Americans United after he left was my good friend David who is coming to San Francisco this weekend for work/visit. David is funny; he used to walk around Georgetown late at night wearing a Michael Myers' mask to scare the locals and tourists.
