I think I was ten or nine years old when someone called my dad to help them go to a hospital because he was very sick and needed to go to an emergency. My father was in a hurry and looked to get the person on time to the hospital and told me to close the door and follow me. I locked the door, and the key was inside, and my father and the man and a sick person came and asked me which key I told him inside. In the end, they called an ambulance because if we waited, he would have died.
