Happily, he's been distracted by his girlfriend lately.
She's a female version of Crossing Guard and stalks him during school hours. Every morning she's standing next to him talking, and he only has time to wave.
I have no idea if she's dating him, but she's awfully keen on standing shoulder to shoulder.
It's been relatively peaceful since the school holidays, except for the one morning when Girlfriend wasn't there, and I heard all about the different numberplates that went past.
I kid you not, he told me about the numberplates he sees; chortling about one that said "hookr", as if that was the first ever joke.
