Are Buttons, Bells and Buzzers a Vanishing Breed? (Mission District, San Francisco)

Some day everything will be activated by our irises. But until then, I plan to enjoy the beauty and tactile satisfaction of doorbells and buzzers.

Stop Being Fearful (Union Square Subway Station, Manhattan)

It took me two days to read this note. On the first, I was carried along by the rush hour crowd, and anyone with sense never stops on subway stairs at such a moment. The crowd is unforgiving (because it's composed of individuals like me who are very unforgiving when someone blocks the flow). The next day, however, I was ready with phone in hand. I waited for the surge of people to pass and then paused long enough to take a snapshot. Although I'm posting this under the date when I took the picture, I'm actually writing this several weeks later and can report that while graffiti often lingers in this city for months and years, this little bit of advice was was scrubbed away a couple weeks ago.
