This has actually happened to me. The neighbor's house had been robbed and she wanted to use my phone to call the police as she was afraid to go inside her house. It was 2AM.
I brought my phone out to her on the porch. If I had not had a long enough cord to bring it out to her, I would have made the call for her. Part of the reason I could not let her in my house is because my dogs would have eaten her.
Even if it was a land line, it could still be a cordless phone, and you could just take it to her on the porch. But, I know you wanted a better answer than that. If there was no indications of danger (strange cars around my house), I would ask her who the neighbor was and what the address was to test to see if she was really seeing the neighbor.
Sadly, I would also evaluate her appearance and judge other features of her to make my determination. If she didn't seem like she had any bad intentions, I would let her in. Since she's a woman and I'm a man, I wouldn't be afraid of her directly doing something violent once she was in the house.
I would be more afraid that she was casing the place for burglars or trying to steal something. I would keep an eye on her while she was using the phone and pay attention to the conversation to see if anything else was suspicious.
If I am alone in the house, I wouldn't respond. There are many cases of crimes that are committed by hypnotizing their victims. One of a teacher in my school who has just taken her pension was hypnotized and all of her lifetime saving were gone.
A student got kidnapped, another lost her phone with the same method. If I have someone else at home with me, I would talk to the lady at the door. I would never let her enter the house, let alone borrow my phone.
I'd let her use the phone. I'm rather confident in my ability to defend myself.. espcially from another woman.. a strange man I may not let in. My house is also full of pointy and shooty things I know how to use.
I wouldn't say home invasion is a big issue in my town either so.. I likely wouldn't worry and would probably even know her unless she was a summer tourist.(very small town).
Explain that you don't feel comfortable letting her come inside (if that's the case) but you're happy to make the call for her.
It would depend on her appearance and how she presented herself. Make sure you lock the door behind the person in case shes just opening the place up for someone else to enter.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
