A childhood belief about around the house

I used to believe (probably from reading to many Famous Five books by Enid Blyton) that every house had a secret tunnel somewhere, you just had to find it. I used to go around tapping walls and things to find them. My suspicions were confirmed when I went on a school trip in primary school to a very very old house, where there were many secrets cupboards tunnels and passages. This made me look even harder when I got home, even though my mom and dad tried to convince me otherwise.

I also managed to convince my sister that when she was asleep at night a tunnel used to open between our house and next door, and the tunnel started above her bed, and I told her stories of how I used to go through the tunnel at night and play games with my neighbours.

We also used to think that it would be really kool if all houses were connected by underground passages that no-one knew about except our friends, so we could visit each other in the night without our parents knowing!
