so... those who are deaf-blind and are afraid/worried about walking anywhere- especially at night have mental problems too? I am deaf but with with 'low vision'/vision issues that aren't the best at night so yes I tend to be a little scared ****less sometimes unless I am somewhere I know VERY well. I will never forget the minor league hockey game I went to with 5-6 other guys. All deaf but four were deaf-blind...the head scratcher? I wound up being the 'lead' for two deaf-blind guys (I lead 2nd guy- hand on my shoulder, third guy had hand on 2nd guy's shoulder) in a line; #2 & 3 both use white canes, #4 was mobile enough to not need assistance. Since it was in a city/area I knew nothing about it was...interesting.
Hmm.
But I can see the OP's point of view- I can see if a person is late deafened and not used to it just yet that they'd be a little freaked while walking because they can't hear anything (like before) around them, behind them etc. A born-deaf already knows to use their eyes and awareness while walking around. Unfamiliar places even for a hearing sighted person can be unnerving too.
Very true RR... well lit areas are unavoidable sometimes though but high crime areas at night I think most people know not to go running around in at night lol. Those who have to walk at night due to shift work probably know tricks to protect themselves or know longer routes etc to avoid any kind of trouble.
