Yay glad you found your phone!
My best ever lost and found was when I was a youngish teenager, wearing my first pair of very special, highly prized dangly silver earrings. I was sitting on the top bunk of my sister's bunkbeds. Rather than using the ladder to get down, I launched myself into space and jumped down. One of my earrings caught on the delightfully old-fashioned frill around her ceiling lightshade in the middle of the room, and came off (it didn't hurt!).
I searched and searched and couldn't find it.
FIVE YEARS LATER, my sister was having her room redecorated, complete with new carpet. The room was cleared, cleaned, and hoovered (my mum is a total clean freak so it would have been hoovered thousands of times in between!), the carpet was taken up, rolled up, and carried out. As the carpet fitters carried it through the kitchen, my mum saw something fall out. Yep, it was that damn earring.
How amazing is that?!
