Benefit

Others say when you meet, they will greet you even if you do not know them. All acquaintances will remember, When you are not known, they are all gone.

That's really the behavior of others, Sometimes they are kind when they need you. But when you are lacking, their hurtful words almost overwhelm you.

You have no benefit, In the eyes of the beneficiary. After benefiting, You are useless.

I have met many, and I have benefited. When you have nothing, they do not need you. You don't have to trust, that's all you need.
