I was on the F train uptown from East Village when an old man got on the train. There were no more seats available, so I decided to give up my seat and offer it to him. I didn't expect the response, though: the man said thanks and told me that I have a great respect for the elderly.
Having just been to an amazing show, I must admit, I was close to having a sentimental moment after that small encounter - but when the train briefly stopped in Rockafeller station, there was this weird hobo lady who walked back & forth the carriage and then lit and smoked a cigarette when the train started to move again, to the annoyance of everyone.
The universe probably told me not to overdramatise things.
