There are signs on the footpath of the A7 that say
BLIND PERSONS
CROSS HERE
And I wondered, is this a notice to blind persons advising where to cross? or is it a notice to drivers to be aware of who is crossing here?
And then I realized that it can be both at the same time, a kind of self-fulfilling prophecy. A masterwork in brevity in signage.
(Smarties replying that blind people can't read the sign: some can, and some have sighted companions.)
@futzle Of course, the sign could indicate where blind people get grumpy 🤔
Perhaps in this spot the footpath is unusually troublesome. So the sign is a warning to others, that in this area the blind people will become angry?
