Esther, that is so cool! I can't believe that happened to you. You hear of this happening, but you always think of it being other people. So great that you were outside when they happened by, and you were able to take them inside for a visit. What age was this person?
I actually know a couple of people who either did that, or had it done to them (meaning, they went back and got a tour, or they were the new home owners who were approached and then gave the tour). It really means a lot to the people who used to live in the house.
I guess we have a lot of memories and emotions tied up in the place that was, in a sense, our cradle for many years.
