Since I've been NY, I met a few people. During our conversation, I found out even though New York have almost everything, 
one of the biggest cities in the world, people who are foreigners here still feel hard to make real friends. (e.g. You have no idea 
the friend you just met today might leave next few days) Me, as a single man, strongly agree with this. Thus, I try to keep the
 moment I have shared with my friends (who left already), but show it as the feeling of loneliness.
