The leaves don't turn yellow all day long, and the people's hearts don't get cold all day long. How to understand this sentence?

Leaves do not turn yellow in one day, nor do people's hearts grow cold all of a sudden. They all need to be accumulated. Use less to accumulate more. People's hearts are hurt little by little, waiting again and again. What comes in exchange is no return, love is ignored again and again, and slowly no longer waits for love anymore, the heart has become cold, the love has gone, and the past has gone with the wind.

Leaves do not turn yellow overnight; hearts do not become cold overnight.

You always turn a blind eye to those who are always nice to you; you always turn a deaf ear to those who often chat with you.

No matter what you hurt, you can’t hurt people’s hearts; no matter what you play with, you can’t play with feelings.

When clothes are torn, they can be sewn; when a heart is broken, there is only pain.

One person's indifference will eventually silence another person.

I always talk to myself too much, but I can’t wait for a sincere greeting;

I always wait for too long, but I can’t see the outline of a figure.

No matter how fiery the heart is, it will gradually cool down; no matter how persistent the person is, he will slowly withdraw.

Don’t mistake feelings for feelings, one day you will know what heartlessness is;

Don’t think that you don’t care, eventually you will understand what coldness is.

People's hearts are relative, exchange truth for truth; feelings are mutual, warm your heart with your heart!
