A friend who can communicate sincerely without any interest disputes is a true friend!
The most basic conditions for being friends are: to be friends with each other is to be friends! .
A friend is not the first person who thinks of you when he or she is in trouble, but the first person who thinks of you when you can help him or her.
A friend who knows that you will try your best to help you when you are in trouble is a true friendship.
In today's real society, good friends are people with economic interests.
Ordinary friends only chat together occasionally, good friends want to take advantage of you, intimate friends are ambiguous, and intimate friends and girlfriends will try their best to help you when you are in trouble (only when your economic environment (good or bad) has changed greatly, you really need to know which is the best friend or the best friend).
People who don't help you when you are in trouble are also friends! That's just a fair-weather friend.
