My friend Michelle has two teenage sons, and I nicknamed them "Null" and "Void". They are twins (not identical, though) and they don't care much for each other. Most of their conversations revolve around the words "gay" and "idiot-boy". It's scintillating stuff to listen to, unless you've got something really fun to do like suck on an old shoe...
I think it's lack of female company that is troubling them.
I note with satisfaction that my last ** mention of got through. So far. I'll be watching...
