Hole in the wall!

I was sure that the sea was much bluer when I looked through the hole in the wall than when I looked over the wall to the same place! I spent a good 20mins trying to see if I was right by taking snaps of the hole then the sea over the wall and comparing them against each other.......... Yes, just as you're thinking, my wife thought I had lost it too!

It was bluer........... or maybe not!
