Remarks by Author: I feel like I haven’t done justice to this topic. It has been on my mind for the past nine days, and I kept writing about it. I made several edits, and at one point, the word count became too high. Later, I felt that not all those details were necessary. Now, I’m wondering if I didn’t explain the bond model clearly enough for readers to understand. I got stuck in the cycle of trying to make this blog perfect, so out of frustration, I just published without further changes.
