Phew, finally caught up with it!

What can I say, the bittersweet tone is a bit too bitter for my taste, but overall the story is pretty good and I enjoyed it alright.

Now, for nitpicking...

> Rhona is the friend Becky mentioned. Pam was Rhona's sister and Alex is the brother, who showed her what the head is good for. ;)

This line:

"At Rhona's house." The little girl shrugged. "A few years ago, her family barbecued her at a party. And her head has been sitting by her parents."

Reads like it's Rhona who was barbecued and made into an onahead.

> "That's no mean feat. After all, I'm your only sister."

That's a good ending, but one line short from being perfect. It should have just one more line going like this:

"True", bobby agreed, and the two of them laughed in unison under Sam's content gaze.
