I have just begun to realise how much ds1 remember via google maps.
He was wandering around a city on google street scene that he doesn't know very well (been there 5 times maybe?) and I realised he was near my aunts house (been there 3 times maybe once as a baby). We haven't seen my aunt for years for various reasons. I think he last went to her house in 2003, maybe 2004. He must have been 3, 4 at most.
Anyway I said to him 'can you find auntie X's house'? He went straight there and pointed to it.
