Everyone has experienced that moment of panic when you realize you forgot a personal item on a plane, bus, train—and in many cases, your Uber. To acknowledge Uber’s most forgetful riders, and to prepare for Mercury falling into retrograde in just over a week, we’ve created The Uber Lost & Found Index.

The Uber Lost & Found Index is a snapshot of our riders’ most commonly forgotten items (there are thousands every week!)—from keys to chargers to wallets—and the most surprising items left behind. It also highlights which cities are most prone to forgetfulness, and which days of the week Uber riders tend to be most forgetful.

We found that phones and rings are the two most commonly forgotten items, with chargers and sunglasses rounding out the top 10. Riders have also left everything from bulletproof vests and potted plants, to pool sticks and kites. Our riders never cease to surprise us!

Coming in at the top of the most forgetful cities in the North America is Los Angeles, California. And which day of the week do Uber riders tend to be most forgetful? We see the most reports on Sundays, presumably from items lost the night before.

The full results are below. Take a look.
