A teen

My son turns 18 today. That makes me offically old, if I wasn't already. We're having a dinner at the local with family friends, a couple of his friends that he's had since we first moved to the Mountains, his mum and sister, and my girlfriend and I.
She's nervous as this is the first occasion on which she has 'joined the family' for an event. It'll be fun, and he says that he can endure it as he'll be thinking of getting his new Wii, which is released tomorrow.
