Thank you for reading and commenting @Summerabbacat, and welcome to the Baxter Boys story. You have nicely picked up on one of the most important parts of the story which is the relationships that people build with each other and the different types of relationships, even if some of them are unlikely on the face of things. Circumstances may bring people together but it is more than circumstances that determine what happens after they meet. What people bring to the relationship has more to do with any successful relationship than what they can get out of it. That said, let's see what happens in this story, but it is safe to say the stronger bond is between Harry and Michael at this stage in the story. Max and Stacy do look like a mismatched pair, but as you point out they have a strong loving relationship, one that encompasses their 'family'.
I understand what you say about Wind Beneath My Wings as it is flogged to death by many, but in this story, it fits well and you make some very interesting points regarding the songs and artists you mention. I may use some of it at some point in the future.
I look forward to reading more of your comments, they are well thought out and interesting.
