This post actually is kind of sad since so much as happened since the TD era
It's a shame that what should have been such a happy era in her life had to end on such a negative note.
In the extremely unlikely case that I ever met Katy, I would have a dilemma. I would want to say something personal to her, rather than just cliches that everyone tells her (that they like her music, that she has a beautiful voice, etc). I would really want to tell her how much the song Teenage Dream means to me, and would want to emphasize my personal connection to the song, and not that I liked it since it was so popular. But I would, at the same time, feel like I'd be rubbing in her face that my marriage worked out better than hers. I'm sure she'd put on a happy face, but I would not want to say anything that could hurt her inside. So I would have a real dilemma.
