That’s the House
If a child starts talking about a random blue house in the middle of nowhere, you’d probably chalk it up to the kid having an overactive imagination. But what if they started claiming that their “other grandparents” came from that mysterious blue house? The OP and their mother were curious to see what the kid was talking about, so they entertained the tyke.
What they didn’t expect was to come across a blue house 45 minutes away while following the directions of a five-year-old who probably couldn’t find their way home from three blocks away. Did the kid use Google Maps? Maybe, maybe not.
