The comment box is both my forum and my filter. So if you've got something to say, and it's sincere, witty, well-worded and includes an email address / URL, I will try to dignify it with an equally thoughtful (or irreverent) response. Make full use of it, especially by random strangers who make unqualified assumptions about me. Patience is not a virtue that I possess in abundance. And in future, if you ever corner me in a small, enclosed space with your bag full of implements and a head full of presumptions, I promise you, there will be a small brick in my bag you will quickly become fast friends with.
