Is It OK To Knock On My Childhood Home And Ask For A Look Around?

I grew up in Malaysia in the 90’s, in a tiny purpose built village in the middle of the rainforest. 10 or so years ago, we went back to visit where we used to go for weekends away and over to the village and local town. We had to hire a driver and car to get us there as it’s obviously not a place tourists visit. He picked us up in Penang and drove us across the east west highway to the village. Much of the top part of the village had been reclaimed by nature but the lower parts had been taken over by people squatters. They had turned our school into a garage (ripping the front wall off) but the set work we painted as children was still there. The swimming pools were taken over by nature and like massive ponds full of water lillies. The last house we lived in was in the lower part of the village, so we went off to check it out. We are stood there, 4 British adults, a Malaysian driver and Malaysian sort of tour guide in a brand new top of the range Mercedes minibus, taking a photo of our old house. Suddenly the door opens and a very confused elderly Chinese man comes out and the tour guide had to explain why we were there and that we had used to live in the house many years ago. We then find the people living in the village are squatters and the guy thought we were here to charge him for living in our old house and there to kick him out. So we are there trying to reassure him this isn’t the case and we are here to reminisce and look around. It was cool seeing the village and what had been reclaimed by nature and what was being used to live in. Our old fish tank was even on the front porch, still going strong!
