Emergency visitors
It's difficult to turn away a visitor who is in need of assistance. It's reasonable to be cautious at first, even if they claim their car has broken down, they urgently need to use the restroom, or they are experiencing a medical emergency. How many individuals nowadays go out without a cellphone? So, why is this person trying to call you on your landline?
If you don't feel comfortable with a stranger entering your home, simply refuse to let them in. Inform them that you can assist them by contacting the police or arranging for a tow truck on their behalf. Someone who has a genuine need will agree right away, whereas a burglar looking to break into your home will not. It's time to call the cops if they become pushy or hostile.
