What happens when the Sisters suffer from Fuck-Deficiency?

Ruby sends this to me via MSN in the afternoon:

RUBY:
REASONS TO BE CHEERFUL
strawberries/ being tickled/ teddy bear/ splashing in the bath/ hiding/ banging things/ wrapping myself up in blankets/ running around naked/ flowers/ being cuddled/ refusing to be cuddled/ Hiding things/ balloons/ Bursting balloons/ Puddles/ jumping/ jumping into puddles/ falling asleep in Smooth arms/ slides/ doggies/ putting things in coffee/

REN:

If you ever send idiotic things like that to me again, you’re out of the peapod!

REN speaks:
I told Ruby i was going to post this on the blog to remind her how moronic she became. It started off as a joke when i said she behaved and spoke like a two-year-old whenever she wasn't not screwed enough. Looks like the theory is true. And she wonders why I smack her on the head ever so often.
But on the other hand, I was thinking.. if this could be the very same reason why I get exceptionally edgy and abusive sometimes...
Why demonstrate physical violence on HER??
Because she lets me. haha.. okay, okay puki pea, you're back in the pod.
