Don't treat friends with a utilitarian heart, because we and friends are just like our relationship with banks. If we usually hold a utilitarian heart, just like taking money, we will take away our feelings bit by bit, and eventually we will break up. On the other hand, if we always associate with friends with utilitarian heart, our network resources will always be exhausted.

Imagine that many friends haven't contacted for a long time, and suddenly a phone call comes and asks you to do something. What would you think? This is really the Sambo Palace. Help, not to mention the previous mutual affection and relationship. It has never been a taste in our hearts.
