Claude's Load-Bearing Seams
Now that I have the full picture, the load-bearing seams are much clearer. They are not merely incidental details around the edges. They materially change how the entire situation needs to be understood, and that is the smoking gun I should have recognized earlier.Claude's load-bearing seams

I’ve been a doctor for 13 years and much of that period has been spent training to be as good a surgeon as I could ever be. I have great family support, a physician wife who…
