You hang out with leftover men and women, at first you don't understand, but after a while you think not getting married is actually pretty good;

You hang out with someone who is a mistress, at first you find her disgusting and think she's dirty, but over time you get used to it, and you might even understand her difficulties, and possibly walk down that path yourself;
You hang out with lazy, procrastinating people who have no goals, and you lose your ambition and passion for doing things, wasting days, lying flat, and idling away your life.
