I'm glad everything worked out okay, seems kind of scary to let the stranger in, but perhaps she'd brought a holiday present and didn't want to accept that she was going to have to travel to another house to deliver it.Then she kept insisting I was Judy's mother even after I told her I wasn't - twice. She handed me a plastic bag with something in it and said for me to give it to Judy.
Did she give any explanation for not having a phone of her own?
