Tangent inbound: your comment is a great example of my rule that whenever you read or hear the word "just", you should think hard about what that means. My wife told me to "just build a retaining wall." That word, "just" does a lot of work in our society.

It's the load-bearing "just". In your case, literally.

Same with "should". I feel like most "should" statements aren't helpful. Something should be done a certain way, but in the end, society should be perfect and we shouldn't have this problem in the first place!
