Alpha, This woman looks like a gipsy beggar woman to me. She doesn't seem to be an unhappy person - she looks much more like a smart person to me. She reminds me a bit of the witch in "Snowwhite". I wouldn't be surprised if when the night falls, that she would stand upright and have no need for her stick anymore. Judging from her skin - particularly the arms, I don't think she is a very old person. I think that she has just found a nice spot in a street of Florence where the tourists are generous. I like the way she's sort of isolated from the surrounding people too.
