This is not a direct true story, thankfully, but I think it points out that the behaviors we dislike seeing in our children are often just a reflection of what we ourselves are doing, even if we don’t realize (or want to acknowledge) it. Do as I say, not as I do!
On an overly self-critical note: what’s up with that arm in panel two? I think that might be the worst appendage I’ve ever drawn in the strip. Good grief.
