the identical twins

Since moving up here 2.5 years ago, selling my Kia Rio,  I have been walking instead of driving. You get to noticing the regulars in the neighborhood. Pictured above is a regular who is usually seen with her identical twin sister.  I don't know if they are homeless. But they always wear identical complex ensembles. If one has a pink hoodie under a red sweater under a lavender coat over a floral dress over velvet slacks over hello kitty socks in gold metallic clogs - then both of them do. But here is the one sister without the other. I have never seen this before. I have seen them both relaxing on a bench in the sun of Yerba Buena park, both with identical purple rolling suitcases, but i have never seen one without the other. I have no idea what their story is. They are colorful inhabitants of these mean streets.
