Article in English: When apologizing, you are likely being very honest and humble.  When that apology is not accepted, it might make you angry, causing your face to tense up or perhaps even turn red.  Work to remain as calm as possible.  Though it is okay to cry or to express sadness, do not beg, plead, or yell. Be genuine with what you are feeling, but do not let your apology be overcome with negative emotional outbursts.  For instance, perhaps your boss rolls his eyes while you are apologizing for missing a deadline.  Instead of furrowing your brows or rolling your eyes too, avoid over-the-top facial expressions, and continue with your sincere apology. Before delivering the apology, practice some self-soothing techniques so that you can be at peace.  Consider meditating beforehand or saying a quick prayer. When your apology is rejected, take a deep breath in through your nose and exhale slowly through your mouth.  Do so until you feel calm and ready to either reopen the discussion or walk away. For instance, if your friend refuses your apology, you can practice deep breathing so that you don't react negatively to them.  No need to breathe loudly as this can be perceived as aggressive.  Make your breaths slow and steady. Though your feelings are likely hurt, avoid being defensive.  Do not insult them just because they did not accept your apology; this will only make matters worse.  If you can think of nothing positive to say, simply say “okay” and walk away. Avoid making comments like “Well, I didn't care if you accepted my apology, anyway” or “You were never a good friend to me.”  Now is not the time for bickering. Try to accept the other person's response, even if it is not the one you want to hear. In the moment,  perhaps an apology is not the best way to mend an issue.  Consider whether or not there are any fixes that you can employ.  You can even try asking them if there is anything that you can do to fix the situation. Show that you're taking responsibility for your actions by thinking about ways in which you can correct...
