If there were a pill of regret for sale in this world, I believe everyone would want to have it, so that after each argument and cold war, you could take a pill and forget everything, and start over. It's such a pity that there is no such medicine, and even if there were, taking the pill of regret all the time would also develop drug resistance. Each argument leaves a little hurt, which accumulates and becomes your burden and his烦恼. No one would dwell on a small argument, but what about two or three times? Many times? All the arguments eventually turn into委屈, and one day, they will explode.
