Blind stuff...of and hit or miss

so do blind dogs have guide humans?

do the blind drunk have guide teetoallers?

does blind lemon pledge (that famous epsilon delta blues guitarist) have a guide track?

and what about hit&run drivers- why is that so bad? what do you expect them to do: miss and run? :-)

I think we should be told.
I would rather see you steppin away from me than go blind, to paraphrase an old song.
