You don't know who is really good to you until you are poor enough to get sick.

If someone is willing to be nice to you, don't toss and turn. There is no perfect person in the world, and it is very rare for a person to be kind to you. If someone follows you from the poorest time, don't be greedy. No matter how developed you are, keep an eye on them. No matter how many people we have experienced, there is only one who can stay with you in the end. You don't know the only one until you are old. No tossing, no greed, just a lifetime.
