Here are some recently overheard remarks in the BS Haus to flesh out that image for you:
Toe: Roo, you can't be a pretty little girl! Put down my purse!
Roo: Dat's my Pokemon love ball, Tove! Give it me'r! Give it me'r! I can't don't want thanks for sharing!
Toe: Mommy, Reuben bonked my penis blanket*!
Toe: Mommy, Reuben poked my bee-bo*!
Toe: Mommy, Reuben is sitting on me and making my feet circle*!
Toe: Mommy, Reuben is pulling on my foot-fingers*!
Roo: Here, Tove, dat's for you, dat's for me and dat's for me and dat's for me...
There are also the daily flying ninja asassin wars with tot-sized golf clubs, Squinkie theft, fruit leather tug-o-wars, and what I can only describe as "butt budging" (this involves an aggressive shoving of one another's hind quarters in order to jockey for the spot closest to Mommy on the couch). Occasionally Roo will forcefully remove a loose tooth from his brother's mouth and Toe will pin Roo down and commence what he announces is "Naughty Reuben spankenbutt time!"
So far, so good though. No one's called the authorities. And, according to Hub (fairly close in age to his own brother, and survivor of his own childhood bro-mance), I have this reassurance: "Unless blood or hammers are involved, it's best to just let them be."
Hence I say, love on, my brothers, love on.
