Then one week I went to stay at my caravan after a long absence.
I opened the door and, for some reason, was overcome with the desire to give it a thorough clean out.
Which is when I found one pair of aviators tucked down behind a squab. Ten minutes later I found another pair at the back of a drawer. And towards the end of the day I found the third pair hanging out in the sunscreen basket.
"Awesome. I've got three pairs of aviators!" I yelled.
I've never lost them again, but having three pairs is not such a great idea. Because people like my husband see them lying around, pick them up and decide they'd quite like to wear them, too.
"Those are mine," I said as he slid into the car reeking of hippy cool.
"They were spare. I thought I'd use them. I think they look good on me, don't you?"
"No, I don't. You're the black Wayfarer guy. I wear the aviators, you wear the Wayfarers. That's how it's always been. We do not wear matching sunglasses."
"Mmm, I think I'll wear the aviators anyway."
I took my aviators off.
"What are you doing that for? Does it really matter if we're wearing the same?" asked my husband.
"Yes, as a matter of fact, it does."
What he didn't know was the night before I had laughed my head off watching a sitcom where a character made fun of a middle-aged couple who were both wearing aviators.
"Tragic old people trying to look cool in their aviator sunglasses," was how the script went.
And here I was, with my husband, being tragic.
Then I noticed that we were also wearing matching black hoodies.
"Why are you wearing your hoodie? I'm wearing mine!" I shrieked.
"I'm sure lots of couples wear similar clothing and sunglasses. When you look at it, there's something quite cute about it, don't you think? Stylish even," he said.
"Take it off," I said. "Now."
He refused. So I took off mine.
We were about to leave on holiday and the last thing I wanted was to be one of those couples you see walking around Europe in matching khaki zip'n'go travel pants, shoes, backpacks and parkas.
I told my husband my fear.
"Oh dear," he said, as he reached into his shopping bag and pulled out two T-shirts. "I bought these for us.
"It's a witty take on Angry Birds except it's NZ Angry Birds. I thought we could wear them when we were in Finland where Angry Birds was invented!"
I threw mine out the window. I hope the person who finds it enjoys wearing it.
