Among the photos of the Bolter (my paternal grandmother), I found one of a house in Devonport, Tasmania which she had some connection with. The Bolter had written the exact address in white ink, as was the habit then. I checked on a couple of sites and the house is still there and I could see it with Street View. I scanned and printed out the photo and sent a copy to owner with a note, including my email address.
Our neighbour back in the eighties gave us a photo of our old house in East Malvern taken just after it was built, 1934 I think. I scanned that and printed it out and sent a copy with a note to the present occupants, including my email address.
R said it was a nice thing to do. I thought so. I realise not everyone is interested in history or buildings as much as I am, not everyone has email, though I did include my name and where I live, so I could be found in the phone book, but there was no response from either.
People have been very kind and helpful to me on the internet over the years. I hope I have always thanked them. I think I have.
Sending the photos cost less than a dollar, nothing, and a little time. A lack of response will not stop me doing such thing again, but I am slightly disappointed. Perhaps I am just being silly and expecting too much. They didn't ask for the photos. I just thought they might find them interesting.
