I truly meant for the next chapter of Band Geek Diary to be ready for posting this weekend, but I was having too much fun with family and friends over the holidays and didn't write like I wanted. I do apologize and promise to get it posted as soon as it's ready (and I also promise that won't be the kind of months-long delay that you readers endured between chapters 19 and 20!)
Since the calendar lines up with the story's calendar, I'll point you to this weekend's adventures in chapter 19. Katie gives up her virginity to John on her 15th birthday on Friday night, but they have to endure John's folks putting on a celebration for Katie that keeps them from continuing the sex. Katie's mom, Becky, gives them a chance on Sunday.
Hang in there. Chapter 39 is coming soon.
