"In the last month, we've left two items in the overhead compartment ... my husband's sports coat and, on another flight, my fleece." When you travel, you're not in "automatic" mode - and are more likely to forget something. People also forget things because there's so much to remember. And once you're at your destination, try remembering the Wi-Fi password at your rental house or your hotel room's number. I travel with three kids, who sometimes do their own "double-check" and leave an item in the room.
