I did recently. I was running around the house getting my luggage packed and I dropped the dogs off at the kennel. When I got home, I put the keys on the dining room table and not in my purse. So when I was finishing packing and transferring everything I need from my purse into my carry-on backpack, I didn't see my keys in my purse, so it didn't get packed. I started locking everything up and the taxi pulled up and closed the door shut. That's when I realized I didn't have my keys.
DH was already on the east coast and he never brings his keys and I always tell him he should. Luckily, we were able to get into the house because DH hid a key.
So funny part is when I got to Philly, my BIL picked me up from the airport. My sister called him as we were headed back to their house, she locked her keys in the house, too. I quickly called my other sister and told her not to lock her keys in the house like we did.
When was the last time you locked the keys in your house?
