It is.
I'm not kidding. :-(
I was beginning to suspect that I had more padding in my posterior, and I asked Michael a few days ago if he thought this was the case.
He tactfully pondered my posterior, and came to no precipitous conclusion -- pleasant or otherwise.
But this morning, he was certain. My caboose is becoming the biggest car of this train!
It's taken us both a bit by surprise. There's truly more of me to love!
