I debated posting this here or on the AO3 comments, but since you posted the a/n here, I figured it made more sense to post my comment here (I'm really anal about internet commenting etiquette)

I totally agree with how you've put the difference between 24/7 and TPE. It's something that I've struggle to put into words, but you did it perfectly. I used to have a 24/7 relationship, and I'm fairly plugged into the community, so I just wanted to let you know that you've done a very good job of understanding the difference.
