I recognized a man as a brother on the Internet.

Generally, people you know online don't know their roots, so it's hard to share happiness and hardship. As the saying goes, people know their faces but don't know their hearts, what's more, you know nothing about them. Can you betray his character and personality just by your chat? Now that you've said share weal and woe, say that you need some money urgently and borrow it from him to see if he can really share weal and woe with you. A person can help you when you are in trouble and in urgent need, and can lend a helping hand when you are down and out without worries. He can give you spiritual comfort, material support and economic help. Then he is a brother who is worth making friends for life. If he hears that you are in trouble, he will ignore it and pretend to be missing. Then he is a boastful and careless wine and meat brother. Don't worship such a brother, I hope you think twice.
