Or not so secret.
That thing you did. Do it again.
I'm not telling: it's a secret.
Never open doors if you don't dare to walk on through ...
In my Grandparents farmhouse, there was a closet that had doors at both ends. One end led into the kitchen and the other into the family room. To get between these two rooms one normally had to go around through the dining room and then the living room to the family room - but us little kids would push through the clothes and such at both ends and made it our "secret passage way".
We had a weather tunnel that led from the House to the Barn. It case of a Blizzrd you could get from the house to the Barn, or use it for shelter in bad weather (tornado). Was it secret, not really. However strangers to our house did not know about it.

Look in the mirror...that's your competition.
No but reading a book about a secret passage inside an ancient tree trunk,lol.
