It started on Abbey’s sixteenth birthday. We’d only been going out a couple of months, and I was coming back from holiday when I realized I hadn’t got her a card. The card shop at the airport had a pretty rubbish selection, and the only vaguely birthday-related one said ‘You are 8 today!’ and had a big colourful badge on the front. I gave it to her that night and she’d cracked up laughing.
After that, it snowballed: every Christmas, birthday and anniversary, we competed to see which of us could give the most random, obscure, inappropriate card.
