But I quite like the slightly surreptitious nature of taking the picture - that is unwitting subjects, but not intrusive pictures (I hope).
It also reveals to the sharp observer which tube lines I frequent the most...
But crucially I notice now just how quickly observational photographs of the world today date - many of the pictures I have taken over the last 6 years of shops and people in Hampstead, West Hampstead and Kilburn have already changed and dated incredibly quickly.
I'm not sure but I guess time will tell...
Until then, I'll leave you with the unremitting notmality of life on the tube in the mid-morning of a weekday.
