This did happen to me. My father moved to a new town for his job while I was away at college. When I returned “home” for that summer, I had no idea where the family was living other than the name of the town, which I had never visited. Thankfully, everyone in the village knew exactly where to find my family!
If they were trying to ditch me, the ploy failed. If they were trying to encourage self-reliance and using my noggin’ to find them, it worked. I’ll go with the latter interpretation.
