ah yes. Line-walking. A challenging activity. What is nice is when we find that it isn't a line, that we are actually in a river, with banks, yes, and with a strong current, but with some room for movement and commonality. 

My guess is that Francis and Franky (father and son) would have had some interesting and tense conversations (or dialogues or both). They did, if I remember correctly, not always see eye to eye while Francis was alive. But Francis was intellectual and thoughtful and respectful and inviting of thinking. 

And you are looking for that, too.
