I don't post a picture of myself because I don't have one. I've never owned a camera in my life, don't have a phone camera, never will have one. I don't have any photos of my son growing up or anything like that. Basically, unlike a lot of people in this world, I have no interest whatsoever in photos.
If someone were to suggest that my avatar shows a lack of honesty, I'd say quite the contrary. It's a bit of joke aimed at myself. Is that valid?
