Not so old BUT
I checked on my maternal grgrandparents house, which is where my grandparents ended up living. (all deceased now) BUT while doing it I noticed that the house my mum and dad lived in before they divorced was standing ((It was across the road)) which amazed me to no end because I burnt it down when I was a child!!!!!
Obviously I didn't burn it all down as someone has rebuilt it and it looks almost the same as photo's I have (from before I burnt it down)
I didn't burn it on purpose,,,,I was trying to clean it up,,,,(long story)
