Hello how may I help you? I need help managing my house. What can I do to help? I want to check if all the doors of my house are locked. Any specific doors, or simply all of them? All the doors of the house. The front door is locked, the back door is not. Can you please lock the back door? Yes, it's now locked. Can you double check if all the doors of my house are locked? Double checking... They are all locked.
