I' m home alone but I took the dog out for a walk. So I took the key of the veranda door to enter again afterwards. But between the veranda (which is directly attached to the living room) and our living room are 2 big doors which you can open and close like a window. It has become a habit to close these doors, which I did as usual, and left through the front door (don' t have a key of that door) without any further thinking. So when I came back I could only enter the veranda. I had to go to the neighbors to call my grandparents (who have a key of the front door and the garage). They had to drive to my home to let me in again 😮
