Until last Thursday when we signed our lease and became legal residents of our abode, we only had one set of keys. We traded them back and forth depending on who was going out or coming back at what time. In order to open the front door you have to have a key - whether you locked it or not. So one day I declared my plans and left. I was locked out, but I was also locked in.
Our house like all the houses here, has a gated yard. The gate locks too. Without the keys, I couldn't open the gate. Without the keys, I couldn't open the door to the house to get the keys to the gate. I could go nowhere. In Spain, could someone starve to death on their front or back porch?! I buzzed the doorbell and Dar came and let me in and then out. There's a phone with a special buzzer for opening the gate without a key.
Last week, we got our keys. So no more being locked in and locked out at the same time, hopefully. But then Saturday, I thought everyone was in the car waiting for me (we were going on a day trip), so I locked the house and ran out. I got to the car and realized I forgot my sunglasses. I rushed back and opened the door to find our house guest standing there. I'd locked her in. She was trying to decide whether to call someone's cell phone or stand in the window and wave. You can't open the door from the inside without the keys once it's locked.
