Streetcar architecture from days of yore, on East Burnside between NE Grand and NE 12th Avenue

It's my understanding that streetcar architecture refers to businesses on the first floor and living quarters on the second floor and above. I'm not sure if these recessed areas existed when the buildings were first constructed or if they happened at some point later. I do like the looks of them. And I've seen plenty of evidence in the windows above, on both sides of Burnside, to lead me to believe that folks live upstairs--lamps, fans, kitchen-window sort of stuff.

The absence of color waits to board the 70 bus

I took this photo looking north at the intersection of NE Sandy, NE 12th and East Burnside. The 70 bus stop is on NE 12th. Perhaps someone is inside the bus at the door, about to step off. I say this because it appears the woman with the white hair hesitates, with her right knee bent, before stepping forward. She seems to be looking straight into the bus, too, which makes me think she sees someone moving towards the door. Or perhaps I just clicked at the split second that captured her beginning to move. What do you think?
