@badala: Thanks, Badala!

@objectif-plume: Thanks, OP! I liked the little heart too. I almost wanted to post this on Valentines' day, but that photo's already been chosen for a long time.

@Per Jorisch: Thanks, Per! I liked that fact too :)

@Srinivas Koduri: No, it's good. Our photographer prefers it that way. Thanks, Srinivas!

@Duncan Galbraith: Oh, I'm a brave man alright, shooting the backs of people's heads <chuckle>. I think Travis is brave, but I also think he doesn't always raise his camera. Many seem to be taken from hip or chest height. Another thought on this sort of bravery, is that the more crowded a train is, the easier it is to take pictures unnoticed. Anyway, I'm glad you liked it. Which Moriyama book do you recommend (not that they're easily available here)? Thanks, Duncan! Oh, yeah, I got interested in the subject because of the headphones over the hat (on a day too warm to need a hat even outdoors) and because her face reminded me of Girl Inchoate. I wondered what's the polite way of asking another photoblogger if you can take their picture.

@Still: Thank you, Still! I tried to make it so you could feel the wool on her hat.

@Dileep: Thank you, Dileep! I find it alternately frustrating and exhilerating.

@William: Thanks, William! If you miss the subway, another one will be along in about three minutes :-)

@Ardeshir Tayebi: Thanks so much, Ardeshir!

@throughsilver: If a symptom of playing too many video games is to see the world as though it were a video game... Thanks for the comment, thoughsilver! I'll have to ponder this some more...

@Martine L.: Trying. Just trying. When I think of candid camera, I think of the "just pour rire" gags show. I'm not that funny or that brave. Merci, Martine!

@Tim: Thanks, Tim!

@Visions by Dean Christopher.: Thanks, Dean!

@H.O: Thanks, Hiro-san!
