There is a woman I see occasionally in downtown, she approached me once when I was sitting in the park smoking a cig. I expected a request for a cig or money or something, but no she just talked to me, somewhat inappropriate but not outrageously so(I answered I was from the USA, she said her brother was killed there).
But she has the broadest craziest wide eyed smile the whole time, and she doesn’t blink!(much)
Everytime I see her she has the same crazy smile and beaming eyes without blinking, it is bizarre. I’ve almost got to believe it is drug induced, but I can only think of a strong stimulant.
