The sign says “full”. Not more. Just “full”.
I love signs with room for interpretations and I love even more to think about possible meanings.
Is this the sign for “Stand here to get full inspiration”?
Or the sign for “Please insert only full doses of life”?
Or “Full trust behind this point”.
Or “This life is fully booked. Try to spend yours elsewhere”?
As always, the truth was much more profane.
