A new "secret passage"

There's something I noticed recently when we were walking home from our last family gathering in London: we have a new "secret passage" nearby. Let me explain: there's an alleyway nearby, there's a wooden fence on one side separating it from the road and on the other side some trees. Now the branches have reached the wooden fence, so it's like there is a natural, live roof over our head when we walk there. It looks kind of mysterious. So yeah, it's a new secret passage. I did not have the opportunity to take a picture of it yet, but I will try to do it soon.
