On my way to class, I overheard two different sets of people talking. One person was offering to buy the other coffee. One girl said, "you have a midterm today, so I'll get you a coffee."
I found it very refreshing that people in NYC really are nice. (I was starting to wonder after I almost got hit by a taxi a few days ago.)
Nonetheless, it put me in a good mood for the rest of the day just knowing that the world is good, people really do care about others.
