When I announced my engagement, my kids thought I must be marrying the school secretary - who had actually walked down the aisle round about the time I was getting down on one knee.
I don't blame them. Even when I was at secondary school, we were convinced the best-looking male teacher would be going out with the best-looking woman teacher; the number two bloke with the runner-up female and so on in a sort of Seven Brides for Seven Brothers arrangement.

All of this talk about marriage has really got my Year 4 girls thinking about wedding dresses and lurve. Nuinda (as I shall call her) was awfully upset when her best friend announced during afternoon registration that Nuinda wanted to marry Ramin. She denied it in floods of tears.
But come home time, the truth emerged.
"Mr Ogle," she whispered coyly, as we walked over to say hi to her mum, "you know the boy I said I didn't love? Well, I do really."
