Playing a joke on a friend, he takes it seriously and haggles over every ounce. What should I do?

No matter what the reason is, the other party takes the joke seriously, so we should explain it in time to avoid breaking up the friendship. Many times, we will be embarrassed because of face, thinking that it is just a joke. As for being really angry? As everyone knows, some things are either what you think or what you think. A friend really has his serious reasons and can't do it for no reason. Therefore, this fault lies with us, and we should bravely accept and correct it. Be sure to explain clearly in time, and I believe he can understand as a friend. Only when friends treat each other sincerely can friendship last forever.
