I've given up on the search for the elusive passport and have made the decision to 'fess up to the authorities that it's lost, and I need to get the gorse out of my pockets and pay for a new one.
My husband found his in that handy little storage space on the passenger door of a car. Of course he did. Quite why it was there we will never know. Unfortunately mine wasn't with it.
I've been through every old box of school stuff, through all the Important Document places in the concertina filing box. Nothing. I did find my 5-year-old swimming certificate when I got first place for the best starfish, but no passport.
Now, just a word of caution: if, like me, you need to renew or replace your passport, get on to it quick. There's a bit of a backlog.
Here's a great wee thing to know though. If you can't make it in to town to get a passport photo taken by a professional - and I highly recommend you do- you can take a pic on your phone. Someone has to take it for you and there's a bit of a process to make sure it fits their criteria but you'll get the hang of it. I did my children's pics and after three hours of submitting photos I finally got one each that they accepted. For my own, I thought great, I can be totally vain and wear my best clothes and go full-on with hair and makeup so I can look like a Kardashian on my passport pic.
